Just to clarify. What do you mean by "When running code in debug mode"? Do you use some debugger like `pdb` or pycharm? |

I guess applying '@reprlib.recursive_repr' decorator to 'events.Handle.__repr__()' function can help. Could you check, please? |

"When running code in debug mode" means we're debug the code. We have used both vscode and pycharm. Same result. |

'@reprlib.recursive_repr' decorator to 'events.Handle.__repr__()' could you tell me which file should I change? and why? |
