error, "Unable to import module 'lambda_function': No module named 'requests'"

Question

I have written an AWS Lambda function in Python which uses the 'requests' library (and so has the line 'import requests').

When I test it, I get the error, "Unable to import module 'lambda_function': No module named 'requests'".

I have zipped the 'requests' library folder and the 'requests-2.31.0.dist-info folder' into an archive and have uploaded this to a new AWS layer within the AWS console and have then added the layer to my function, but I still get the error.

Any idea what I've done wrong or missed?

Answer

Hi,

While creating the lambda layer zipped file, please make sure you zipped the content of the folder with the code, and not the folder itself [1]. \
Furthermore, please follow this troubleshooting guide [2].

Answer

Hi,

please make sure that the AWS Lambda layer that you created has the required folder structure, see https://docs.aws.amazon.com/lambda/latest/dg/packaging-layers.html.

Specifically, that the distro folder is within the `python` folder.
