I was trying to follow the tutorial here: https://codelabs.developers.google.com/codelabs/slides-api#1
But the links don't work anymore. Even the "Report a mistake" button in the bottom left side leads to a 404 error.

Do consider fixing it.

in auth.js:

If the TOKEN_DIR exists, the error will always be thrown and the token will never be stored.

function storeToken(token) {
  try {
    fs.mkdirSync(TOKEN_DIR);
    fs.writeFileSync(TOKEN_PATH, JSON.stringify(token));
  } catch (err) {
    if (err.code != 'EEXIST') return err;
  }
  console.log('Token stored to ' + TOKEN_PATH);
}

Should be:

function storeToken(token) {
    try {
        fs.mkdirSync(TOKEN_DIR);
    } catch (err) {
        if (err.code != 'EEXIST') return err;
    }
    try {
        fs.writeFileSync(TOKEN_PATH, JSON.stringify(token));
    } catch (err) {
        return err;
    }
    console.log('Token stored to ' + TOKEN_PATH);
}

Google slides api returns a response from the slides.presentations.get endpoint that, if there is an image in the slide, contains image metadata in the pageElements object"

{
    contentUrl: 'https://lh5.googleusercontent.com/8///LONG HASH///',
    imageProperties: {
      outline: {
        outlineFill: [Object],
        weight: [Object],
        dashStyle: 'SOLID',
        propertyState: 'NOT_RENDERED'
      },
      shadow: {
        type: 'OUTER',
        transform: [Object],
        alignment: 'BOTTOM_LEFT',
        blurRadius: [Object],
        color: [Object],
        alpha: 1,
        rotateWithShape: false,
        propertyState: 'NOT_RENDERED'
      }
    }
  }

In my project I am polling for slide changes since that data isn't available. The problem is that every time you git the endpoint, slides api returns a Different URL for the image used in the slide. why on earth would this be the case? It also does not invalidate the prior url, so every time we call the api we generate new duplicate urls. is

Everything after step one is incorrect. There is no dropdown with New Service Account, and so on. If you intuitively walk through the wizard to create the service key, there is no way to download the JSON.

I'm getting an error when I run the project on Step 8:

• Start generating slides. --

  getting new auth token...

Enter the code from that page here: events.js:183
throw er; // Unhandled 'error' event

(I think this has to do with how I created an OAuth2 Client (Step 5). I have a similar issue at that point in my SPL - I was looking at the codelab to see if you guys had the fix.)
