werkzeug >=3.0 is required, but raises error in patch_flask

[eschibli]

werkzeug 3.0 removed the version attribute, which is accessed in the patch_flask function that runs on startup.

Line 33 in create_app.py should not be necessary anymore since werkzeug>=3.0 is required now.

I am also facing the same issue and it's failing all my deployments. Is there any fix available?

2024-11-10 14:54:18,146 W [71] azmlinfsrv - AML_FLASK_ONE_COMPATIBILITY is set. However, compatibility patch for Flask 1 has failed. This is only a problem if you use @rawhttp and relies on deprecated methods such as has_key().

Not sure deployments fail due to that error.
Paste full log and check also issue #3415 (azureml-examples).

Sure will check it out. I am also facing error "
Failed to test model: Network Error" once it finishes
