Welcome to Microsoft Q&A Platform!Thank you for reaching out! To help us understand the issue better, could you please provide more details about your deployment setup and any errors you're encountering?
- Have you tried deploying the Azure Function App using the Azure CLI or Azure Portal instead of Visual Studio Code?
- Are you able to run the function locally without issues?
Also, hoping that you are using Python 3.11 runtime version in the Azure portal for the Function App.
Looking forward to your response so we can assist you further!
