Mypy error when accessing flask.request.json

[skonstant]

I use mypy to validate my project, I upgraded from flask 2 to flask 3 and now I see plenty of errors when I try to access the json property or flask.request

I just have a top level

import flask

Then:

j = flask.request.json # "Request" has no attribute "json"

Mypy: "Request" has no attribute "json" [attr-defined]

Environment:

• Python version: 3.13.0
• Flask version: 3.1.0

I can't reproduce this issue with the information provided. Creating a file with the given content does pass when running mypy --strict.

We found the actual problem; in case someone else bumps into this: we still had types-Werkzeug in our requirements.txt, like types-Flask it is outdated for Flask 3 and must be removed.
