firebase / functions-samples Goto Github PK

This is the error

FIREBASE WARNING: {"code":"app/invalid-credential","message":"Credential implementation provided to initializeApp() via the "credential" property failed to fetch a valid Google OAuth2 access token with the following error: "read ECONNRESET"."}

How to fix?

I'd like to resize an image stored in Firebase Storage with Firebase Functions.

Based on this example : https://github.com/firebase/functions-samples/blob/master/quickstarts/thumbnails/functions/index.js I try to write a function triggered by a Database event.

Here is the most interesting part of the code :

const gcs = require('@google-cloud/storage')();

...

const bucket = gcs.bucket('...appspot.com');
const originalFilepath = myObject.picture1Url;
const tempFilePath = '/tmp/myThumbnail';

console.log('1');

return bucket
    .file(originalFilepath)
    .download({
        destination: tempFilePath
    })
    .then(() => {

        console.log('2');

    });

Everything looks fine to me. However the code never go to the console.log('2'); and I get this error :

Error: read ECONNRESET
    at exports._errnoException (util.js:1026:11)
    at TCP.onread (net.js:569:26)

Does somebody know what could be the error?

Thank you

In order to get the right ref in a similar function I wrote, I had to replace $hookId by {hookId} here:
https://github.com/firebase/functions-samples/blob/master/minimal-webhook/functions/index.js#L28

Is this something that needs to be updated in the example?

Hi there,

How can I split my functions in its own files. I have tried to use require command, but it seems that I can't reimport resources like firebase-admin.

I am planning to write a lot of functions and put them all in index.js does not sound good.

Thanks in advance

On the quickstart/email-users show an example of sending an localized Welcome e-mail message.

Hi, I followed the readme on full-text search for cloud functions. Adding,modifying or deleting the blog-posts will trigger an error. Same for adding,modifying and deleteing for search/query/{queryid}.

I created an account on algolia then get the ApplicationID, and Admin API Key.
firebase functions:config:set algolia.key="<ApplicationID"> algolia.secret="<Admin API Key">

As a longtime Firebase developer using Emberfire I am beyond excited for Functions.

Are there going to be any Emberfire specific integration examples? @tstirrat @jamesdaniels

Thanks to everyone involved. This is truly amazing stuff.

Unhandled rejection

We have been implementing the quickstarts/email-users/

With a bit of trouble and some tricky kind of error in every step always but we've managed to get to the final steps.

Nevertheless, on the last part (the test to trigger the Functions) as we got no email we checked the Registry tab in the Functions section of the Firebase Console and we found the error mentioned. So the Functions were correctly saved, the trigger is being fired correctly in both cases (new and deleted accounts) but when the Function tries to send the email it returns the error mentioned Error: Invalid login: 535-5.7.8 Username and Password not accepted.

We have already followed the process mentioned in the "Learn more link" included in the error (Verified password, Allowed less secure apps, and DisplayUnlockCaptcha button) with two different email accounts in GSuite (obviously redefining the node vars and redeploying the functions in both cases as Node asks) but it keeps saying the same, even after the third change of account, redeploy and less secure apps allowance.

Any idea on what could be the matter? Or should we try with an account outside Google's domains?

Hello,

Do you have any examples integrations firebase and stripe with cloud function?
Coud you give me link?

Thanks a lot

I am currently using this approach for notifications on receiving a message from a sender.

Everything seems fine but when i kill the app I dont receive notifications.

I saw some answers regarding it that i should use just data message and receive in onMessageReceived()but its not working for killed app. What should i do?

Hi @nicolasgarnier

I am having the following error while deploying the Bigquery. Please note that the npm is already install and the dependancy is added in my package jsom. Thanks

Is it possible to add summaryText and style in notification?

In node-gcm:

var message = new gcm.Message();
message.addData('title', 'My Title');
message.addData('message', 'My second message');
message.addData('style', 'inbox');
message.addData('summaryText', 'There are %n% notifications');

Using the Thumbnail quickstart, followed all directions, deployed, enabled billing, etc.

I get this error in the log:
Function killed. Error: memory limit exceeded

In the Child count example, having copied the DB structure, the following code:

exports.countlikes = functions.database.ref('/posts/{postid}/likes').onWrite(event => { return event.data.ref.parent.child('likes_count').set(event.data.numChildren()); });

likes_count always becomes 0

trying workarounds produces even more irrational results, like the count increases sometimes, sometimes it does not increase, some other times it becomes 0 again.

There's an Stackoverflow question about this:

Try running "npm install" in your functions directory before deploying.

Hi, I'm trying out the image resizing demo. Deployment throwing error:

 Deploy Error: Failed to configure trigger GCS Bucket: product_images

My images are inside product_images folder and my code looks like this:

  const object = event.data;
  const fileBucket = object.bucket;
  const filePath = object.name;
  const contentType = object.contentType;
  const resourceState = object.resourceState;

  if(!filePath.match(/product_images/)) {
    console.log('not product_images bucket');
    return;
  }

  if (!contentType.startsWith('image/')) {
    console.log('This is not an image.');
    return;
  }

  const fileName = filePath.split('/').pop();
  // Exit if the image is already a thumbnail.
  if (fileName.startsWith('thumb_')) {
    console.log('Already a Thumbnail.');
    return;
  }

  if (resourceState === 'not_exists') {
    console.log('This is a deletion event.');
    return;
  }

  const bucket = gcs.bucket(fileBucket);
  const tempFilePath = `/tmp/${fileName}`;

  return bucket.file(filePath).download({
    destination: tempFilePath
  }).then(() => {
    console.log('Image downloaded locally to', tempFilePath);
    // Generate a thumbnail using ImageMagick.
    return spawn('convert', [tempFilePath, '-thumbnail', '64x64>', tempFilePath]).then(() => {
      console.log('Thumbnail created at', tempFilePath);
      // We add a 'thumb_' prefix to thumbnails file name. That's where we'll upload the thumbnail.
      const thumbFilePath = filePath.replace(/(\/)?([^\/]*)$/, `$1thumb_$2`);
      // Uploading the thumbnail.
      return bucket.upload(tempFilePath, {
        destination: thumbFilePath
      });
    });
  });
});

Not sure what it means.

Hello,

I deployed stripe, registered new user which created in "stripe_customer".

How can I use this - /users/{userId}/charges/{id}.
userId is like "cus_AIUNyLkyv8mUUQ"

what is "id"?
How can I add amount to this request?

Thanks

Are their any good examples of the Stripe example written in Swift?

Hi,

I've copy/paste the moderate-images example and when I'm uploading an image in Firebase Storage, it executes the cloud function like there was a loop. To stop it, I have to comment the code and deploy again.

Here is the copy/pasted code. The only difference is that I have removed to google-cloud-vision part and blurred the image every time.

// functions/index.js

'use strict';

const functions = require('firebase-functions');
const mkdirp = require('mkdirp-promise');
const gcs = require('@google-cloud/storage')();
const exec = require('child-process-promise').exec;
const LOCAL_TMP_FOLDER = '/tmp/';

/**
 * When an image is uploaded we check if it is flagged as Adult or Violence by the Cloud Vision
 * API and if it is we blur it using ImageMagick.
 */
exports.blurOffensiveImages = functions.storage.object().onChange(event => {
  const object = event.data;
  const file = gcs.bucket(object.bucket).file(object.name);

  // Exit if this is a move or deletion event.
  if (object.resourceState === 'not_exists') {
    return console.log('This is a deletion event.');
  }

  // Check the image content using the Cloud Vision API.
    return blurImage(object.name, object.bucket, object.metadata);

});

/**
 * Blurs the given image located in the given bucket using ImageMagick.
 */
function blurImage(filePath, bucketName, metadata) {
  const filePathSplit = filePath.split('/');
  filePathSplit.pop();
  const fileDir = filePathSplit.join('/');
  const tempLocalDir = `${LOCAL_TMP_FOLDER}${fileDir}`;
  const tempLocalFile = `${LOCAL_TMP_FOLDER}${filePath}`;
  const bucket = gcs.bucket(bucketName);

  // Create the temp directory where the storage file will be downloaded.
  return mkdirp(tempLocalDir).then(() => {
    console.log('Temporary directory has been created', tempLocalDir);
    // Download file from bucket.
    return bucket.file(filePath).download({
      destination: tempLocalFile
    });
  }).then(() => {
    console.log('The file has been downloaded to', tempLocalFile);
    // Blur the image using ImageMagick.
    return exec(`convert ${tempLocalFile} -channel RGBA -blur 0x8 ${tempLocalFile}`);
  }).then(() => {
    console.log('Blurred image created at', tempLocalFile);
    // Uploading the Blurred image.
    return bucket.upload(tempLocalFile, {
      destination: filePath,
      metadata: {metadata: metadata} // Keeping custom metadata.
    });
  }).then(() => {
    console.log('Blurred image uploaded to Storage at', filePath);
  });
}

And here is a screenshot of my dashboard when I only uploaded one image called "oss2.png"

If you have any input on it, that would be great!

Thanks!

I think problem with

currency = functions.config().stripe.currency || 'USD';

How can I configure it?
Thanks

@nicolasgarnier

Sir, do you have any idea how I can do the reverse charge, meaning, I can pay my user.
Thanks to your advice, I was able to create my fiebase users charges, but I have no idea about how to pay my users. Stripe recommend the connect stripe api, but their documentation is true mess.

WOuld this be done in a webview? any other suggestions?

I'm having issues with Access-Control-Allow-Origin in combination with Firebase Cloud Functions.

I followed the examples to protect my https endpoints to make sure that only users with a valid token can access certain eindpoints.

I configured cors en imported the cors module. The strange thing is that I encounter completely random origin errors. Sometimes the request is valid and other times the request is invalid.

Why I can't see /users/{userId}/""charges""/{id} in my database directory upon account creation ?

Thanks

I was able to implement everything you provide in readme to integrate firebase with stripe. But, when I create a new user in firebase after i deploy the stripe from firebase cli, i cannot see the account in Stripe. I tried everything, deploy with test key, secret key, publishable key, I was unable to see my new account created in stripe sdk.
Please help.

Hi guys, thanks for the examples , i am trying to get started with cloud functions but when i want to test uppercase function example there is a weird behavior , {pushId} param from test is not being correctly passing to the function , here is the logs :

the database path from test is : messages/1111/original

  Cloud Functions
    makeUpperCase
Uppercasing undefined input
      ✓ should upper case input and write it to /uppercase
    addMessage
      ✓ should return a 303 redirect

As you can see, there is a "undefined" in uppercase function , i checked event.params then the result was a empty object {}.Im just curious about this behavior I will try to debug.

Hello

When you prepare documentations how use stripe and firebase?

Thanks

This is awesome. Thank you for making it happen!

The links are broken, in the following Readme page: https://github.com/firebase/functions-samples/tree/master/limit-children

They are:
https://github.com/firebase/functions-samples/blob/master/limit-children/function/index.js
https://github.com/firebase/functions-samples/blob/master/limit-children/function/package.json

When they should be:
https://github.com/firebase/functions-samples/blob/master/limit-children/functions/index.js
https://github.com/firebase/functions-samples/blob/master/limit-children/functions/package.json

Hello,

Could I save cards for customer through cloud function?

Thanks

We're getting asked this a bunch.

Can I use it with Express middleware?

Looking at the Big Query import example, I see that it only updates BigQuery with the onWrite event.

Does it make sense to extend this example to also "backfill" BigQuery with the existing data?

I could be misunderstanding the code though. Does it already do this i.e. when you deploy this function, the onWrite will get triggered for all the existing entries in firebase, and not just the newly created ones?

When multiple users registered under one device, and all of them have same token generated, how to send the FCM to specific user?
