unsupported operand type(s) for |: '_GenericAlias' and 'NoneType'

[chabbly]

Thanks for the great custom nodes! I am getting this error after installing and import is failing:

comfyui/ComfyUI/custom_nodes/ComfyUI_Custom_Nodes_AlekPet module for custom nodes: unsupported operand type(s) for |: '_GenericAlias' and 'NoneType'

Hi. Can you give more information about the error. And what is the python version, please update it to 3.10 or higher.

I am using python 3.8.5 to juggle a different dependency -- perhaps that is the issue.

I think this is the full error message:

Hi. I looked at the logs, the whole point is that python 3.8 does not support union type "|" (https://peps.python.org/pep-0604/#add-a-new-operator-for-union-type1-type2), https://stackoverflow.com/a/76712732/23512000 . As an option, I already wrote above, update the python version to 3.10 or higher.

• Or remove module googletrans from the environment (/home/users/u6933473/chatGPT_analysis/env) and install the version https://github.com/ssut/py-googletransor . Or install version old version on your environment pip install googletrans==3.1.0a0
• Or edit the code in the file "/home/users/u6933473/chatGPT_analysis/env/lib/python3.8/site-packages/googletrans/models.py" line 42

parts: List[TranslatedPart] | None

to this

from typing import List, Union
parts: Union[List[TranslatedPart], None] = None

• Or as an option, remove the GoogleTranslateNode (if it is not needed) by cutting the code from my __init__.py file and deleting the folder in /custom_nodes/ComfyUI_Custom_Nodes_AlekPet/GoogleTranslateNode

PS: It is best to update the python version, because the problem is not in my nodes, but in the version googletrans library, which does not support versions below 3.10.
