UnableToFindDownstreamRouteError, Failed to match Route configuration for upstream path: /, verb: GET

[pseudorasbora]

hi:

upgrade from 22.0.1 to 23.0.0:

it throws error "bad gateway, 502" when using method "get". methods "put/post/delete" work well.

ocelot log: requestId: 0HM5DM6ULMR8I:00000002, previousRequestId: no previous request id, message: Error Code: UnableToFindDownstreamRouteError Message: Failed to match Route configuration for upstream path: /api/xxx, verb: GET. errors found in ResponderMiddleware. Setting error response for request path:/api/xxx, request method: GET

now it works after rollback to 22.0.1.

thanks!

Hi

Could you attach ocelot.json file and C# app startup code (configuring services etc.) please? Also full exception call stack is desired.

But it is better to upload full app code for review.

So, please provide more information!

@pseudorasbora Is it so difficult to attach more details here? We cannot decide having so short description!

@AlyHKafoury Are you online?

sorry, it's online.

@ggnaegi Please consult this developer! 🙏 I expect misconfiguration issue... I'm a bit tired of such inquiries...

hi:

upgrade from 22.0.1 to 23.0.0:

it throws error "bad gateway, 502" when using method "get". methods "put/post/delete" work well.

ocelot log: requestId: 0HM5DM6ULMR8I:00000002, previousRequestId: no previous request id, message: Error Code: UnableToFindDownstreamRouteError Message: Failed to match Route configuration for upstream path: /api/xxx, verb: GET. errors found in ResponderMiddleware.

now it works after rollback to 22.0.1.

thanks!

Hello @pseudorasbora a lot of new features and changes were introduced in the release 23. We are going to release 23.1 next week. Could you try the new release first (a bug with the request content has been addressed)? If the issue persist, we will try to find a solution with you.

:warning: Could you maybe change Ocelot log level and provide us more verbose logs?

Thanks!
