run completed record omitted status

Error message

run completed record omitted status

What it means

Thrown by TryFrom<pb::RunCompletedV1> for the run completed record when the run status proto enum is UNSPECIFIED. Every completed-run record must carry a concrete status (Succeeded/Failed/Cancelled/Panicked/Cancelling); UNSPECIFIED is the proto3 default meaning the producer never set the field, so conversion is rejected as InvalidData.

Solutions

1. Have the producer always set status (set_status(pb::RunStatus::Succeeded) etc.) on RunCompletedV1
2. Fix run-finish code paths so the terminal status is recorded before the event is emitted
3. Treat UNSPECIFIED at decode time as a malformed record and skip/log it
4. Add a producer-side assertion that status != Unspecified before serializing

Example fix

// before
let rec = RunCompletedRecord::try_from(msg)?; // status Unspecified
// after
msg.status = pb::RunStatus::Failed as i32; // or set_status(...)
let rec = RunCompletedRecord::try_from(msg)?;

fn has_status(msg: &pb::RunCompletedV1) -> bool {
    msg.status != pb::RunStatus::Unspecified as i32
}

match RunCompletedRecord::try_from(msg) {
    Ok(rec) => rec,
    Err(e) if e.kind() == io::ErrorKind::InvalidData => { log::warn!("run-completed missing status: {e}"); return; },
    Err(e) => return Err(e),
}

When it happens

Trigger: RunCompletedRecord::try_from on a message where `status` was left at its default UNSPECIFIED — the emitter forgot set_status(), or the value was zeroed out during serialization/storage.

Common situations: Prost/proto3 default-value pitfalls (enum defaulting to 0/UNSPECIFIED when unset); a new completion path in the runner that reports status late; corrupted event records.

Understand the failure class

Background: Invalid enum value errors: "Unknown type", "Invalid scope", "must be one of" — when a string is not on the library's allowed list — this error's family across 23 libraries.
