How to monitor celery logs in heroku

I want to monitor celery logs from an app in Heroku. I did some research and found a couple of repos that deploy a new heroku app which uses flower to monitor.

Problem: I followed those instructions and deployed a new app to heroku but I get this error message:

2023-08-03T11:09:17.312149+00:00 app[web.1]:   File "/app/.heroku/python/lib/python3.11/site-packages/tornado/web.py", line 88, in <module>

Not sure what I have done wrong? Please bear in mind that I'm not a software developer.

It is not collections.MutableMapping, it is collections.abc.MutableMapping, your code is trying to access the class from the wrong path.

My guess is that the code you found is python 2.x, where I think MutableMapping was directly under collections. There were a lot of changes between python versions 2 and 3 though.

Current stable python version is 3.12 - look for more recent projects that support 3.7 and up and you'll have more luck.
