Solutions

1. Validate the value against the allowed enum range before constructing the message.
2. Ensure client and server use matching protobuf definitions; regenerate bindings if versions differ.

When it happens

Trigger: Occurs when a protobuf enum value received over IPC has no matching variant; conversion rejects the unknown value.

Common situations: Typical of version skew between client and server, or a malformed/corrupted IPC message.
