Build failing on flask app with uWSGI

I have a flask app that uses uWSGI that used to work just fine but now keeps failing on build giving this error:

I even tried to undo the changes on the new commit and tried to deploy a version of the app that worked before but the same error keeps coming up on build. Would appreciate any help and feedback on this issue

Hi @aditeyashukla, welcome to the Render community!

After doing a lot of searching surrounding this error one thing I can think of is that pip install is using a version of uWSGI that is causing conflict. Can you try pinning the version in requirements.txt to a version that you used in the previous build?

Hi @tyler, thank you!

I tried specifying the version in the requirements.txt file that last worked (2.0.19.1), and it still gives the same error. I even tried using <=2 and the build still failed
