I uploaded the zip file, but afterwards received the warning: "The deployment package of your Lambda function "pdftk" is too large to enable inline code editing. However, you can still invoke your function." *pdftk is what I named the lambda function

I decided to at least 'test' it by pressing the test button and going w/ their default event (since I thought it wouldn't matter what we passed to it), but that failed w/ the output:
{ "errorMessage": "2020-01-18T00:05:36.522Z e8312ad1-165e-4255-a5d9-6b5c50b374f8 Task timed out after 3.00 seconds" }

I thought the example was supposed to be a straightforward way to test a simple run of pdftk in lambda, but I don't know where I might've misunderstood/missed a step.

my project's files & directories: https://i.stack.imgur.com/ZahqK.png

I have a Lambda Function, and the code I have uploaded to the Lambda Function is a zipped folder of my /Archive directory.

When creating Lambda Layer, do I upload a zipped PDFtk binary as 1 layer? and the libgcj as a 2nd layer? Or do I upload both of them in 1 layer?

Do I upload my lambdazip.sh in a Lambda Layer?

From what I understand, many of the people who run into this "[ERROR] Runtime.ImportModuleError: Unable to import module 'lambda_function':" have issues because of their Lambda Handler.

My Lambda handler is: lambda_function.lambda_handler so this doesn't appear to be my issue.

Another common problem I've noticed on StackOverflow, appears to be with how people are compressing & zipping the files they upload to the Lambda Function.

Do I need to move my lambda_function.py? Sometimes this CloudWatch error occurs because the lambda_function.py is not in the ROOT directory.

Does my survey directory need to move?

I think the folders & directories I have here may be causing my issue.

Do I need to zip the directories individually?

Can I resolve this error by Zipping the entire project?

For more information, I also have a Lambda Layer for PDF Toolkit, called pyPDFtk in the codebase. In that Lambda layer is a zipped /bin with binaries inside.

If there is anything I can alter/change within my code or AWS configuration, please let me know, and I can return new CloudWatch error logs for you.

Hello I get this error:

  { Error: Command failed: pdftk './pdf1.pdf' './pdf2.pdf' cat output /tmp/tmp-808h0P0DOq5v1
  /bin/sh: /var/task/bin/pdftk: Permission denied

should I use chmod? does it matter if I have ubuntu?

Ubuntu (and I think Debian too) add a drm_fix patch to their copy of pdftk. This makes it work on PDFs that have an owner password set to enable certain PDF features, but are not encrypted. I'm working on a project where PDFs come in from weird sources, so this is quite necessary.

You can see the patch here: drm_fix.txt

Or get it from Ubuntu here: http://packages.ubuntu.com/trusty/pdftk

I didn't see any option to upload binaries to AWS Lambda. As per the readme

AWS Lambda supports binary dependencies by allowing them to be included in uploaded ZIP files.

Could you please provide the reference link or tutorial for this.

I am getting error "Command terminated by signal 11 " while I have used binary version of file on my godaddy shared account...

Can you please help me to get solution of this ?

Hey,

I got an error while trying to test the example function after uploaded it to Lambda from S3.
this is the error that I get:
{
"errorMessage": "Command failed: /bin/sh: /var/task/bin/pdftk: Permission denied\n",
"errorType": "Error",
"stackTrace": [
"",
"ChildProcess.exithandler (child_process.js:658:15)",
"ChildProcess.emit (events.js:98:17)",
"maybeClose (child_process.js:766:16)",
"Socket. (child_process.js:979:11)",
"Socket.emit (events.js:95:17)",
"Pipe.close (net.js:466:12)"
]
}

configurations :
IAM Role - lambda_basic_exectution :
{
"Version": "2012-10-17",
"Statement": [

"Action": [
"logs:CreateLogGroup",
"logs:CreateLogStream",
"logs:PutLogEvents"
],
"Resource": "arn:aws:logs:::*"
}
]
}

I gave full permissions (chmod 777) to each file in the zip archive before uploading it to S3
What did I missed ?
