ASP.NET http.route appears to be incorrect when exception handlers are invoked about opentelemetry-dotnet HOT 3 CLOSED

Ah and you also mentioned that you're using net8. The instrumentation in this repository only emits metrics for net6 and net7. With net8 the http.server.request.duration metric is emitted natively by the ASP.NET Core itself.

See comment in the release notes.

Fixed an issue where the http.route attribute was not set on either the Activity or http.server.request.duration metric generated from a request when an exception handling middleware is invoked. One caveat is that this fix does not address the problem for the http.server.request.duration metric when running ASP.NET Core 8. ASP.NET Core 8 contains an equivalent fix which should ship in version 8.0.2 (see: dotnet/aspnetcore#52652). (#5135).

You'll need to update to ASP.NET Core 8.0.2+

@tyler-boyd I think this was fixed by: #5135

Would you mind trying 1.7.1 or newer and report back?

Thanks for the quick replies, I didn't see that linked issue because I was searching for http.route (which isn't explicitly mentioned).

Updating to the latest version of these libraries did the trick, I should have tried that before opening an issue 🙂 Thanks again!
