I received an answer from the other post.
The root cause is that Limbda's runtime is Linux system. The Python zip file need to be packaged from a Linux environment. After installing WSL (Amazon Linux 2) on my Windows, I packaged the Python code from WSL, the Limbda function worked as expected.
The error you're encountering is typically due to a mismatch between the Python version used to create your deployment package and the Python runtime version specified for your AWS Lambda function.
In your case, you've created the deployment package using Python 3.11, but your Lambda function is using the Python 3.10 runtime. This discrepancy can lead to compatibility issues, as certain modules or functionalities may have changed between different Python versions.
To resolve this issue, you should ensure that the Python version used for packaging your dependencies matches the Python runtime version of your Lambda function. Here are the steps:
- Create a virtual environment: Use Python 3.10 to create a virtual environment on your local machine. This isolates your project and allows you to install dependencies without affecting your global Python installation. You can create a virtual environment using the
venv
module:
python3.10 -m venv myenv
- Activate the virtual environment: Before you can start installing or using packages in the virtual environment, you'll need to activate it. On Unix or MacOS, use:
source myenv/bin/activate
- Install your dependencies: Now that you're in your virtual environment, you can install your dependencies using pip:
pip install -r requirements.txt
- Create your deployment package: After installing your dependencies, you can create your deployment package. Make sure to include your function code and any dependencies:
zip -r my_lambda.zip .
- Upload your deployment package: Finally, upload your deployment package to AWS Lambda.
By ensuring that your deployment package is created with the same Python version as your Lambda function's runtime, you can avoid compatibility issues and ensure that your function works as expected.

Yusuf, Thank you so much for the detailed instructions!
I currently only have Python 3.11 installed on my Windows 10 machine. Do I need to install Python 3.10 to create a virtual environment of 3.10?
Since I didn't have Python 3.10 executables to create a 3.10 virtual environment, I uninstalled Python 3.11 all together and installed Python 3.10. After that I followed the instructions above, but still received the same error messages. Any more idea and advice?
