I am trying to make a gRPC request to my API which is behind a cloud load balancer. The cloud load balancer is a TCP load balancer that supports HTTP/2 but, for some reason which is beyond our control, rejects any requests that do not have a HTTP/HTTPS scheme. This is currently working for clients connecting from various languages (C++, Go, Python) so even though this is odd, gRPC is working.
When I manually overwrite the scheme in the Postman request path, postman gives me the error shown here
I cannot manually set the header in a gRPC request using Postman as the header tab is missing for this request type.
Is there a way to force postman to set the scheme to HTTPS for gRPC requests?
