Hi been looking for a solution for this for hours, need a fresh set of eyes. When deploying my app to heroku the logs have it crashing showing that a worker failed to boot and an import error shortly before that. Now the current import error is from werkzueg but before I updated flask I was getting an import error from Jninja for 'escape'.
I've also seen that an improper procfile may cause this but I'm pretty sure my procfile is correct. I'm not setting any ports in either my front/backend and have set the endpoint on the frontend to the url heroku gives me for the build with my specified endpoint.
tldr I don't know what is causing this error Link to the github for more detailed code https://github.com/Jmumford45/Heart_Prediction_ML
app.py is inside Backend
Procfile: web: gunicorn --chdir Backend app:app
