grpc-json transcoder: stream return type always returns 200 even in case of errors #5011
Description
Bug Template
Title: *grpc-json transcoder always returns 200 OK with response body [] when rpc return type is stream *
Description:
The grpc-json transcoder always returns 200 OK with response body [] when rpc return type is of type stream. If the gRPC api returns an error or throws an exception, it still returns 200 with body '[]'. The response content-type is always 'application/grpc (for successful and unsuccessful calls).
Expected behaviour: The response content type should be application/json and errors should be reflected in the status code.
Repro steps:
I came across this issue while writing a blog post about Envoy and grpc transcoding. Please just focus on the ListReservations rpc for reproduction.

package reservations.v1;
// Creates separate .java files for message and service
// instead of creating them inside the class defined by
// java_outer_classname
option java_multiple_files = true;
// Class that will contain descriptor
option java_outer_classname = "ReservationServiceProto";
// The package where the generated classes will reside
option java_package = "nl.toefel.reservations.v1";

}
rpc GetReservation(GetReservationRequest) returns (Reservation) {
// {id} is mapped into the GetReservationRequest.id field!
option (google.api.http) = {

};
}
// lists all the reservations, use query params on venue or timestamp to filter the resultset.
rpc ListReservations(ListReservationsRequest) returns (stream Reservation) {
// use query parameter to specify filters, example: ?venue=UtrechtHomeoffice
// these query parameters will be automatically mapped to the ListReservationRequest object
option (google.api.http) = {
get: "/v1/reservations"
};
}
rpc DeleteReservation(DeleteReservationRequest) returns (google.protobuf.Empty) {
// {id} is mapped into the DeleteReservationRequest.id field!

};
}
}
