Describe the bug

After very fresh repository init and the amplify pull I have added a comment to function then tried to push by amplify push. I was forced to do a migration and after that I see this:

I found similar reports at aws/aws-cdk#12536, however nothing of mentioned there helped to resolve my particular issue. If you could provide some info about what do I need to run amplify-cli from sources - that would be very useful.

Expected behavior

proper amplify push

Reproduction steps

1. amplify pull
2. change function
3. amplify push

Hey @n3b 👋 thanks for raising this! To clarify, was a change made to a Lambda function that is attached to a Lambda Layer? I see from the screenshot it appears our layer version is erroring out. I also have a few follow-up questions:

• what resource were you prompted to migrate?
• were there any changes made to the Lambda or Layer outside of Amplify CLI (i.e. in the AWS Console)?
• does amplify function push mitigate the issue?

[n3b]

Hey @josefaidt thanks for helping!
The function I changed is not attached to the layer. I did change that layer itself (I had to mention it, sorry) by removing the deprecated layerVersion from parameters.json. Additionally amplify-cli does some changes too - there is a prompt "Accept the suggested layer version configurations".

• The lambda layer itself. "Amplify has updated the way Lambda Layer versions are managed. In order to take advantage of the newest features and bug fixes, a one-way migration is required....."
• No, the layer contains node_modules only. The function wasn't modified via console too as far as I know.
• it doesn't, same issue.

Hey @n3b thanks for the clarification!

No, the layer contains node_modules only.

To further clarify, does the layer also contain the package.json and associated lockfile?

[n3b]

@josefaidt yes, those are there. The modules are installed locally too, not sure whether they are ignored or not.
I've checked multiple Node versions from 12 to 16 - the issue is consistent and doesn't depend on that.

Hey @n3b can you check to see whether the lambda layer distribution zip is empty? Are you able to cd into that directory and install dependencies without error?

[n3b]

hey @josefaidt yes it is empty 22b zip file, and yes I can install dependencies:

"dependencies": {
    "axios": "^0.21.1",
    "cross-fetch": "^3.0.6",
    "graphql-tag": "^2.11.0",
    "mysql": "^2.18.1"
  }

[josefaidt]

Hey @n3b thank you for clarifying! Unfortunately I am unable to reproduce this issue using a sample lambda layer with a few dependencies as I can see my distribution zip archive is around 40MB. Would you mind sending your amplify/ directory as a zip archive to amplify-cli@amazon.com? I'd like to take a further look at the setup

[n3b]

Hey @josefaidt unfortunately I can't do that due to privacy. We've found a quick workaround by getting rid of the layer completely.

[josefaidt]

Hey @n3b I have revisited this issue with another layer and the only way I'm able to reproduce this issue is if I delete all files in the layer's lib/nodejs/ directory and opt/ and push. Since the layer has been removed entirely and I am unable to reproduce I will close this issue for now. In the event you choose to use a Lambda Layer and this issue arises, please reply back to this thread with minimal reproduction steps and we can re-open to investigate further 🙂
