LGTM! Not sure if it would make sense to update the name in both request and reponse handler for best effort but also I'm not aware of hono internals for routing.

nit: A comment explaining what this actually does would be helpful, but not worth a CI rerun

Also, is this always the correct one?

I can include a comment in another PR.
And yes, -1 gets the last matched path which is the one where it's routed to.

Hono error events were showing a wrong culprit (
?(index)) because the transaction name was only being set in the response handler. When an error was thrown during middleware execution,captureExceptionran beforeresponseHandlerhad a chance to update the span name and isolation scope transaction name.This PR moves the span and transaction name update into
requestHandlerso the correct route name is set before any middleware or route handler executes. TheresponseHandlernow only captures errors.Also switches from
routePath(context)(last matched route so far) toroutePath(context, -1)(final matched route) which avoids wildcard patterns like/error/*leaking into the transaction name.Also adds another test for route parametrization when using middleware.
Closes #20399
