2.2.0 bug: type object 'Flask' has no attribute 'try_trigger_before_first_request_functions'

[kdieudonne-adeo]

when running gunicorn with flask 2.2.0 i get this error as soon as i start the program, downgrading to 2.1.2 fix this problem

edit: might have been better placed in issues, didn't see it before posting

before_first_request is deprecated and will be removed in Flask 2.3. As part of that, some internals were refactored for performance, including try_trigger_before_first_request_functions method. What code were you using that was calling this method? This method was not intended as a public API, and will be going away completely in the next feature release, so it's probably better to address whatever is using it.

it seems it's dd-trace that use this, they have an issue already opened on their git-hub about it so hopefully it'll be updated soon
thank you for the help
