AI-type nodes in Port workflows have no onFailure configuration option, unlike WEBHOOK, KAFKA, UPSERT_ENTITY, and INTEGRATION_ACTION nodes which all support failure handling. When an AI node fails : whether from hitting the tool-call iteration cap, a model error, or a timeout: the workflow run terminates immediately with zero output, no downstream nodes execute, and no fallback action (such as posting a default comment or triggering a notification) is possible. For workflows where AI nodes are the primary actor in customer-facing automations like PR review or issue triage, a single failure means a completely silent, unrecoverable run with no signal to the end user.
