ImportError: cannot import name 'init' from 'pushover' (/usr/src/app/src/python-pushover/pushover/__init__.py)

Question

I'm running this container (it was forked from code that I cobbled together before, but has been enhanced since then).

It used to work, but after recent changes it now fails with the error:

Traceback (most recent call last):
  File "/usr/src/app/app.py", line 20, in <module>
    from pushover import init, Client
ImportError: cannot import name 'init' from 'pushover' (/usr/src/app/src/python-pushover/pushover/__init__.py)

Looks like this docker image is pulling in https://github.com/almir1904/python-pushover/

Any ideas how to go about debugging and fixing this?

I was going to reach out to https://github.com/volschin, but there are no contact details so I cannot.

Examining the docker image file, I can see the folder /usr/src/app/src/python-pushover/pushover exists, and __init__.py is in there.

I tried removing and re-pulling the container down.
