I am following this tutorial:

https://learn.microsoft.com/en-us/azure/app-service/quickstart-python?tabs=flask%2Cwindows%2Cvscode-aztools%2Cvscode-deploy%2Cdeploy-instructions-azportal%2Cterminal-bash%2Cdeploy-instructions-zip-azcli

I followed it exactly, using the VS Code instructions. The code runs successfully on my computer. When I clicked to deploy to my Azure web app, VS code said the a app had deployed successfully, but in the web app's logs I am getting this error, over and over again: 2025-04-18T19:43:37.988878817Z python: can't open file '/tmp/8dd7eafea962688/app.py': [Errno 2] No such file or directory

Here is the complete log:
