django 3 - import ipdb; ipdb.set_trace() - Runtime Error

Just installed django-3.0, I'm used to insert ipdb to stop runtime and inspect functions. With previous version it was working fine. Is there any way to get it work?

I faced the same issue. If you are using Python 3.7 (which it looks like you do, based on your trace) You can use the new Python breakpoint() instead.

Basically, you would replace

import ipdb; ipdb.set_trace()

By

breakpoint()

Check https://www.python.org/dev/peps/pep-0553/ There you can find out how to set up more fancy breakpoints as well.
