Lost a few expense-tracker entries because a webhook call to Google Sheets failed silently (rate limit) and the workflow just... stopped. No retry, no alert.
Fix: each node has a "Retry On Fail" setting under node options, off by default. Turned it on for the Sheets node with a 3-attempt cap and a short backoff.
Worth auditing every external-call node in a workflow for this, not just the obvious ones.
