Check whether search failed before the transaction flow
A failed customer search can happen before a payment, deposit, withdrawal, or transfer is even selected. If the selected failed request is a search endpoint, the PM summary should call it a search or account lookup issue first.
Nearby transaction calls may still matter, but they should be treated as context until Engineering confirms the user-facing error happened later in the lifecycle.
Watch for auth and session clues
HTTP 401, HTTP 403, and auth-related failure codes often point to session sequencing, expired context, or recovery behavior. That does not mean the customer did anything wrong. It means the workflow attempted a request without the access context that backend expected.
A clear ticket says that the HAR points to an auth or session-type failure during customer search, then gives Engineering the correlation ID.
Look for a later successful retry
If a later search succeeds after login or session refresh activity, the incident may be about error handling. The user saw an error, but the system later recovered.
That distinction matters. Engineering may need to review retry behavior, session readiness checks, or whether the UI should suppress a transient backend failure.
