Enum string values not supported by grpc gateway

[archanabs19]

Request:

Response is "unknown value "DIFF" for enum mode"
gRPC Gateway is accepting only int values but protoc-gen-swagger is sending string values. Ideally, gRPC Gateway will accept both string and int values of an enum.

This happens if you configured your JSON marshaler to parse enums as ints. By default it should parse strings. See https://github.com/grpc-ecosystem/grpc-gateway/blob/master/runtime/marshaler_registry.go#L16. You can use a custom marshaller to support both strings and enums.

Please join the grpc-gateway support channel on Gophers slack for this sort of debugging.

EnumsAsInts value is not set. So, by default, its taking string itself. Still, its unable to parse.

Sorry to be brusque but I think this is a misconfiguration issue. Maybe you could join the support channel (#grpc-gateway) on Gophers slack (https://invite.slack.golangbridge.org/) and I can help you there.
