Flask API deployment fails on App Service

Question

I'm getting the following error when trying to deploy my Flask API to App Service. Followed the docs exactly. My environment is called venv.

I'm using Windows to create my API and deploying to a python 3.9 runtime (Linux; no Windows option available). SCM_DO_BUILD_DURING_DEPLOYMENT is set to true (in the .deployment config)

What could be the issue here?

Answer 1

Upgrading python to 3.9.12 and recreating the virtual environment worked for me.
