I'm trying to deploy a Flask app to Vercel and get this error, which I believe is because of the python-pushover package.
Here is the error log which gets generated after I run vercel --prod on the terminal.

I have python3.9 installed in the Pipenv environment.
Has anyone encountered this error before and can provide a solution?
Thanks!
