Passing of JWT token to Upstream service for Validation


I am working on a POC where I am trying to validate JWT token in my upstream service The JWT token is generated by a Custom GRPC Plugin after user is successfully authenticated.

I want to know pass this JWT token yo upstream service so that it my upstream service validate these tokens.

I configured the request header "Authorization: Bearer $tyk_meta.jwt "
but still tokens are not passing to my service.

I am following this repository: .
