Hi rbill

I am sure someone on here can help, but we’ll need more information:

what guide have you followed?
were you able to get your gRPC server up and running?
you said “it is not really working” - what were the exact symptoms?

Thanks

i take the guide from tyk documentation, i get the gRPC server up and running ( the server i use GitHub - grpc/grpc-java: The Java gRPC implementation. HTTP/2 based RPC ).
The symptoms are tyk engine does not call at all the gRPC servers when calling api.

Thanks

Hi rbill,

can you share your tyk.conf as well as your Gateway logs ?

Thanks,
Kos @ Tyk Support Team

This should be set to true and you need to set the URL for the gRPC server.

Also, this forum has markdown support - makes it easier to read code if you use it :wink:
