EDIT:
This fork can be helpful

json_encoder and json_decoder attributes on app and blueprint, and the corresponding json.JSONEncoder and JSONDecoder classes, are removed from Flask version 2.3.0.
So, it shows JSONEncoder = json.JSONEncoder
AttributeError: module 'flask.json' has no attribute 'JSONEncoder'
For more refer: https://flask.palletsprojects.com/en/2.3.x/changes/#version-2-3-0
From pipenv change to portry, lock Flask in 2.2.5
From pipenv change to poetry, lock Flask in 2.2.5
📌 pin flask and Werkzeug

downgrading to
flask==2.2.5worked for me! No longer getting this errorAudiosutras commentedon Mar 30, 2024
Is this a bug that will be fixed or are we to use @idoshr fork going forward. I think downgrading isn't the solution.
