Flask2.3.X JSONEncoder deprecated about flask-mongoengine

[jrypel]

in the meantime, pinning flask == 2.2.5 helps.

I think that this could be helpful

#537

EDIT:
This fork can be helpful
https://pypi.org/project/flask-mongoengine-3/

downgrading to flask==2.2.5 worked for me! No longer getting this error

Yeap, can confirm the same problem.

[iammustafatz]

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'

Is this a bug that will be fixed or are we to use @idoshr fork going forward. I think downgrading isn't the solution.
