Why is the AWS Python Lambda function showing an error message saying "requests" module is not found?

edit

The error message is indicating that the "requests" module, which is a third-party Python library used for making HTTP requests, is not installed in the AWS Lambda environment.

To resolve this issue, you can add the "requests" package to the deployment package that you upload to AWS Lambda. You can do this by either including the package in the same folder as your Lambda function code and zipping the entire folder, or by using a package manager like pip to create a package specifically for your Lambda function.

Here are the steps to add "requests" package:

1. Create a virtual environment for your Lambda function:

python3 -m venv my-lambda-env

1. Activate the virtual environment:

source my-lambda-env/bin/activate

1. Install the "requests" package:

pip install requests

1. Copy the lambda function file along with the installed packages to a new folder:

mkdir lambda-deploy
cp lambda_file.py lambda-deploy/
pip install -r requirements.txt -t lambda-deploy/

1. Zip the contents of the lambda-deploy folder:

cd lambda-deploy
zip -r ../lambda-deploy.zip *

1. Finally, upload the zipped file to AWS Lambda and test the function.
