Support for charset other than UTF-8 in grpc plugin

[Mohit Kumar]

Hi All

We are using grpc as a plugin for opensource gateway (tyk) where we are facing one issue while dispatching the request to grpc server. Error is as following:

rpc error: code = Internal desc = grpc: error while marshaling: string field contains invalid UTF-8

By seeing the error it looks like grpc plugin is not supporting char set other than UTF-8.

Is there any configuration in grpc so that we can add support for special characters other than UTF-8.

Reference Issue: https://community.tyk.io/t/tyk-gateway-not-supporting-non-utf-8-characters/6707

Thanks

Hi Mohit,

are you sure that you are not mixing up a field index?
I have seen this very error when one side was using a repeated field and the other side a string field on the same index.

Hi @Tobias

We are using the same protobufs as recommended here https://github.com/TykTechnologies/tyk/tree/master/coprocess

We have not defined any repeated field ourselves.
