sys.exit() with custom message returns error when run in IPython console in PyCharm

Question

I have the following (very simple) Python script that I'm trying to run in PyCharm:

import sys
sys.exit('My custom message')

In the "Run/Debug Configurations" window of PyCharm, if "Run with Python Console" is unchecked, the execution of the script works fine and provides:

My custom message

Process finished with exit code 1

However, if "Run with Python Console" is checked, the execution is performed with IPython and provides an error:

Traceback (most recent call last):
  File "/snap/pycharm-community/267/plugins/python-ce/helpers/pydev/pydevconsole.py", line 331, in do_exit
    import java.lang.System

    module = self._system_import(name, *args, **kwargs)
ModuleNotFoundError: No module named 'java'
During handling of the above exception, another exception occurred:

    os._exit(args[0])
TypeError: 'str' object cannot be interpreted as an integer

I'd like to test my codes in IPython and don't know how to fix this error. I think my code is correct, so this should be a bug in PyCharm.

Many thanks for your help!
