gRPC Issues GetExecutionResultForBlockID

Hello! I have a query to the gRPC server that I’d be curious is an issue on my end or the server’s.

Looking at using this method:

GetExecutionResultForBlockIDRequest exeResult = new GetExecutionResultForBlockIDRequest()
                BlockId  = blockResp.Id
ExecutionResultForBlockIDResponse exeResp = client.GetExecutionResultForBlockID(exeResult);

But I am met with an unimplemented error:

Status(StatusCode="Unimplemented", Detail="unknown method GetExecutionResultForBlockID for service access.AccessAPI", 

Seems like an odd error if the method is in the API docs.
