Unable to import module lambda function No module named lambda function

Question

Hi Guys,

I created one lambda function using python. But I am getting this below error at the time of running.

Unable to import module 'lambda_function': No module named lambda_function

How can I solve this error?

Hi@akhtar,

This error appears when you haven’t named your code file or function correctly. You need to go to Lambda -> Functions -> Your Function -> Configuration and check the value in the Handler field.

The format should be fileName.handlerMethod.

Hope this will solve your error.

I would like to share a very basic mistake which will also cause this issue. While compress (Zip) the Lambda_function before upload, please execute compression (zip) where all required PY and import modules are located. Do not compress the parent folder where entire files are stored.

When we open the <file.zip>, it should display the scripts and modules and not the parent folder.

can't see handler field under configuration
