Console error "grpc-status", "grpc-message" while data successfully come back

[zsluedem]

I am using a nginx proxy which is compiled according to docker example in the repo.

I send a request to the proxy and it can receive the data correctly while the console would log a lot of errors.

Refused to get unsafe header "grpc-status"
Refused to get unsafe header "grpc-message"

I think you should add this to your nginx config to expose these headers to the browser:
add_header 'Access-Control-Expose-Headers' 'Content-Transfer-Encoding,Grpc-Message,Grpc-Status'
Hope this helps

Yes you need to white list those headers in your nginx.conf

I see. We probably miss that in our own example nginx.conf. We should probably fix it.
