Python 3.10 layer broken (ImportModuleError)

[dverheijden]

Description

When using the new Python 3.10 compatible new relic layer (e.g. arn:aws:lambda:eu-west-1:451483290750:layer:NewRelicPython310:1), our application fails. When deploying the python example and modifying the terraform code, I get the same error.

[ERROR] Runtime.ImportModuleError: Unable to import module 'newrelic_lambda_wrapper': Failed to import module 'app': No module named 'app'

Steps to Reproduce

Deploy the lambda python example with the newest new relic layer and python 3.10 (see also newrelic/newrelic-lambda-extension#157). Deployment then succeeds but testing fails with the above error.

Expected Behaviour

It should be able to import the module

Relevant Logs / Console output

[ERROR] Runtime.ImportModuleError: Unable to import module 'newrelic_lambda_wrapper': Failed to import module 'app': No module named 'app'

Must be specific to their example code as I was able to use the lambda layer in my own code without problems. Perhaps I could compare the two and find the solution 🤔

Any update on this, The issue is with other layers also (3.7,3.8)

Thank you for reporting this. We have reviewed this issue and it looks like we may have a bug in the parsing logic for imported handlers. We are working on a fix for this and will update you on our release timeline once we have a better sense of it.

Hi everyone! We have published a likely fix for this issue. Would you be able to try upgrading to the latest layer for your Python runtime and validate that the error has gone away?

After updating to layer version 9, this problem went away. Thanks for the fix!
