ashb opened a new issue, #26802:
URL: https://github.com/apache/airflow/issues/26802

   Converted back to issue as I've reproduced it and traced the issue back to https://github.com/apache/airflow/pull/24362

   ### Apache Airflow version
   
   2.3.4
   
   ### What happened
   
   I used to be able to use ipdb to debug DAGs by running `airflow tasks test <dag_name> <dag_id>`, and hitting an ipdb breakpoint (ipdb.set_trace()).
   
   This no longer works. I get a strange type error:
   
   ```  File "/usr/local/lib/python3.9/bdb.py", line 88, in trace_dispatch
       return self.dispatch_line(frame)
     File "/usr/local/lib/python3.9/bdb.py", line 112, in dispatch_line
       self.user_line(frame)
     File "/usr/local/lib/python3.9/pdb.py", line 262, in user_line
       self.interaction(frame, None)
     File "/home/astro/.local/lib/python3.9/site-packages/IPython/core/debugger.py", line 336, in interaction
       OldPdb.interaction(self, frame, traceback)
     File "/usr/local/lib/python3.9/pdb.py", line 357, in interaction
       self._cmdloop()
     File "/usr/local/lib/python3.9/pdb.py", line 322, in _cmdloop
       self.cmdloop()
     File "/usr/local/lib/python3.9/cmd.py", line 126, in cmdloop
       line = input(self.prompt)
   TypeError: an integer is required (got type NoneType)```
   
   
   
   ### What you think should happen instead
   
   I should get the ipdb shell.
   
   ### How to reproduce
   
   1. Add ipdb breakpoint anywhere in airflow task.
   import ipdb; ipdb.set_trace()
   
   2. Run that task:
   Run `airflow tasks test <dag_name> <dag_id>`, and 
   
   ### Operating System
   
   Debian GNU/Linux
   
   ### Versions of Apache Airflow Providers
   
   2.3.4
