I am facing same issue :(

Answer 2 · 2023-06-01T16:57:07.000Z

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
