Thanks. Any clue on the docs CI error? I would say to add to nitpick_ignore.

Nope, it's really hard for me to understand where this is coming from. Tried using "AnyValue" in util/types.py but does not change anything.

Appear to work fine with the flask implementation after updating the create_histogram calls for HTTP_SERVER_REQUEST_DURATION:

Thanks. Any clue on the docs CI error? I would say to add to nitpick_ignore.

Nope, it's really hard for me to understand where this is coming from. Tried using "AnyValue" in util/types.py but does not change anything.

We can probably use a TypedDict or just add ("py:class", "AnyValue"), to nitpick_ignore and see if it works:

Moved to TypedDict, thanks for the hint!
