Root Cause

The client sent an integer value that does not correspond to any valid enum constant defined in the protobuf schema.

generic

中文

客户端发送了一个整数，该整数不对应protobuf模式中定义的任何有效枚举常量。

Workarounds

  1. 95% success Ensure the enum value is within the defined set. 
    validStatuses := map[int32]bool{0: true, 1: true, 2: true, 3: true}
if !validStatuses[req.Status] {
    return fmt.Errorf("invalid status: %d", req.Status)
}
  2. 90% success Use the generated enum constants from protobuf. 
    req.Status = pb.Status_ACTIVE // Use the constant instead of raw integer

Dead Ends

Common approaches that don't work:

  1. Ignore the error and assume the server will accept any integer. 100% fail

    The server validates enum values; invalid ones are rejected.

  2. Use a random integer within the range hoping it matches. 90% fail

    Only specific integers are valid enum values; random ones will likely be invalid.
