InvokeSync stage failing on fresh deployment

[vostokbike]

It looks like syncing files to the bucket fails with the following error:

Action execution failed
The AWS Lambda function aws-git-backed-static-website-SyncLambdaFunction-1FVC60HABK1WL failed to return a result. Check the function to verify that it has permission to call the PutJobSuccessResult action and that it made a call to PutJobSuccessResult.

Can you please advice on how to go from here?

What is the output in CloudWatch Logs?

Please check for sensitive information before posting here.

I apologize, github notifications got the better of me. If this is helpful in any way, CloudWatch log for the failing function:

Please try updating your "SyncLambdaFunction" AWS Lambda function with the latest version of the code in s3://run.alestic.com/lambda/aws-lambda-git-backed-static-website.zip

You can do this in that function's AWS Lambda console page with "Code entry type" of "Upload a file from AWS S3" and set "S3 link URL" to "https://s3.amazonaws.com/run.alestic.com/lambda/aws-lambda-git-backed-static-website.zip". Other attributes of the AWS Lambda function can remain the same.

You can then push a change in your Git repository, or go to the AWS CodePipeline console and click [Release change] on your pipeline page to run the pipeline again.

I followed your instructions but get the following error:

22:29:22
local variable 'source_dir' referenced before assignment: UnboundLocalError Traceback (most recent call last): File "/var/task/index.py", line 86, in handler shutil.rmtree(source_dir) UnboundLocalError: local variable 'source_dir' referenced before assignment

Would you be able to update your stack so we do not need to do manual changes to the stack since the function is managed by cloudformation?

[ehammond]

I think I have the CloudFormation stack and AWS Lambda deployment ZIP file in sync everywhere now.

You can either start a new stack, referencing existing resources, or upload the SyncLambdaFunction as described above.
