Grpc-web not return exactly grpc status always response 2 Incomplete response #1417

Closed KP-story closed 3 weeks ago

KP-story commented 3 months ago

I gen code using a command protoc -I=./src/proto \ --js_out=import_style=commonjs,binary:./src/generated \ --grpc-web_out=import_style=typescript,mode=grpcweb:./src/generated \ $(find ./src/proto -iname "*.proto") When I sent request that was not valid, Grpc web always response 2 incomplete response , even though my response headers contained the 'grpc-status' and 'grpc-message' fields."

@KP-story Thanks for the report!

Do you mind following this following Typescript example, and check how things are looking different between that and what you have? https://github.com/grpc/grpc-web/blob/master/net/grpc/gateway/examples/echo/ts-example/README.md

Without knowing your whole setup, it's hard to know what's wrong. So it would be easier if you compare the wire data against the demo we have.

HI, My backend was written by rust tonic web. I always response null with grpc-status and grpc-message in metadata. Is it valid ?

@KP-story As I see you are using CloudFlare might I recommend checking if you have access to the CloudFlare Dashboard for that website, go to the Network tab, and scroll to the bottom and make sure gRPC is enabled so it knows to proxy the gRPC API connection. https://developers.cloudflare.com/network/grpc-connections/

Hi, I have just updated the configuration in Cloudflare, but it's still showing an error. I wonder whether the response Content-Length being equal to zero is the cause of the error.

@KP-story Same problem. Did you solve it?

KP-story commented 3 weeks ago

Yes, I have just added "grpc-status" and "grpc-messages" to the "Access-Control-Allow-Headers" in the preflight request. Vào 19:42, Th 4, 12 thg 6, 2024 Zichao Yang @.***> đã viết:
