Zapier errors / Schema
The app returned "Contact id or email is required" (422)
Cause
A required identifier (contact ID or email) was empty or unmapped in the action step, so the destination app rejected the request as unprocessable.
Fix
Open the action and verify at least one required identifier has a non-empty mapped value. Check the Zap history data-in panel to confirm the mapped field has data for the failing record. Add a Filter before the action to halt when the identifier is blank.
