Answer 1

Hi @Joshi, Shubham the error message you're facing indicates an issue with the importlib_metadata module in your Python environment on Azure. That module is used for package metadata inspection in Python versions 3.8 and above. The

**ImportError: cannot import name 'Sequence' from 'collections'**error suggests a potential incompatibility between the pathlib and collections modules in your environment.

The importlib_metadata module might not be installed in your Azure Python environment, even though it's present locally. It seems like there might be subtle differences between your local Python environment and the one on Azure, leading to compatibility issues.

Follow these steps to try resolving the issue:

1. Install importlib_metadata: There's a high chance the module is simply missing. You can install it using pip:

pip install importlib_metadata

Run this command on your Azure app service or virtual machine where your code is deployed.

1. Check requirements.txt: Ensure your requirements.txt file explicitly lists importlib_metadata as a dependency. If it's not present, add it and redeploy your application.
2. Review Environment Compatibility: If installing the module doesn't resolve the issue, consider these:

• Double-check that the Python version on Azure matches your local environment. You can verify this using python --version on both machines.
• In rare cases, conflicting packages might cause issues. Try creating a clean virtual environment on Azure and installing only the required packages from your requirements.txt.

Hope that helps.
