MsgStore missing for execution

Error message

MsgStore missing for execution {} during normalization setup

What it means

After creating the execution process record, start_execution looks up an in-memory MsgStore for the new process; it must have been registered by a prior setup step. If it is absent the process record is removed from the map and this error is returned, aborting the execution during normalization setup.

Solutions

Retry the execution — if it was a transient race, a new attempt registers a fresh MsgStore.
Check whether another task removes entries from msg_stores and ensure it doesn't target just-created processes.
Ensure single-flight per workspace so concurrent start_execution calls don't clean each other's stores.
If reproducible, capture logs around process creation and file a bug: the store registration path is skipping insertion.

Defensive patterns

Strategy: retry

Try / catch

match start_execution(...).await {
    Err(e) if e.to_string().contains("MsgStore missing") => {
        tokio::time::sleep(Duration::from_millis(500)).await;
        start_execution(...).await
    }
    other => other,
}

Prevention

Avoid concurrent operations on the same execution process (single-flight per process id).
Don't cancel/cleanup a process between creation and its first execution.
Report persistent occurrences — in-memory state should not diverge from the DB.

When it happens

Trigger: start_execution reaching the msg_stores() lookup when the store for execution_process.id was never inserted or was evicted — e.g. internal race, prior cleanup removed it, or a bug skipping store registration.

Common situations: Concurrent cancellation/cleanup deleting the store between process creation and lookup; restarting parts of the service losing in-memory state while DB rows persist; rapid follow-up calls racing with process teardown.
