How can I use breakpoint inside a Hypercorn funtion for Python 3.9

Question

I am using Python 3.9. I am unable to use ipdb.set_trace() inside an Hypercorn process. Please note that this works in Python 3.7.

My code:

#!/usr/bin/env python3

import ipdb

async def app(scope, receive, send):
    ipdb.set_trace()  # DEBUG

When I run (hypercorn hello_world:app) I get following error message:

❯ hypercorn hello_world:app
--Return--
None
> /home/alper/trade_bot/bot/hello_world.py(7)app()
      5
      6 async def app(scope, receive, send):
----> 7     ipdb.set_trace()  # DEBUG

ipdb>

ipdb>

    if self.quitting: raise BdbQuit

Here ipdb> does not accept any input like c, n... How can I do debugging using breakpoint (ipdb.set_trace()) inside a Hypercorn process, if possible?
