Solutions

1. Include the required 'pane_type' field in the protobuf message before sending it.
2. Verify the sender populates all mandatory fields; add a presence check before conversion.

When it happens

Trigger: Occurs when a protobuf message received over IPC omits the required field; deserialization fails instead of using a default.

Common situations: Occurs when a client or plugin sends an incompletely populated message, often from a version mismatch or hand-crafted payload.
