Unable to import module 'lambda_function':

Question

When I am trying to test my python code on AWS Lambda I am getting the following error.

Response
{
  "errorMessage": "Unable to import module 'lambda_function': No module named 'lambda_function'",
  "errorType": "Runtime.ImportModuleError",
    "stackTrace": []
}

These are the basic Setup steps which I followed to push my code into AWS Lambda:-

• First rename your main.py file as 'lambda_function.py'
• Change the name of your 'main' function to 'def lambda_handler():'
• ZIP the File
• Go to AWS Lambda Console, Create Function.
• Provide the FunctionName - 'Demo'
• Choose Python 3.9 Runtime (or 3.7/3.8)
• Let the architecture be 'x86_64'
• Rest configurations be acceptable. Hit the 'Create Function' Button
• There will be a tab/dropdown named 'Upload From'
• Choose the.zip File
• Upload the File
• Click on the 'Test Button'
• Click the configure test event.
• Provide the event name as 'Test'
• Clear the JSON Values and provide empty JSON- {}
• Save it.
• Test the Lambda Function

But after doing this I am getting this error

"errorMessage": "Unable to import module 'lambda_function': No module named 'lambda_function'",
  "errorType": "Runtime.ImportModuleError",

I have made sure to check my Handler Info .

My code - Here I am trying to invoke execute_AWS_TF() function using lambda_handler()

import connect_mongoDB

def lambda_handler():
    connect_mongoDB.execute_AMS_TF()

Your lambda_function.py is in a subfolder called AWS_REPORT... . So you have the tell that to aws. The hendler info should be:

AWS_REPORT.../lambda_function.lambda_handler

Off course AWS_REPORT... must be replaced by the actual name.
