One bad item makes a polling trigger retry the same item forever and block everything behind it

The same error repeats every polling interval

Verified 2026-09-02 · Confirmed by 0 builders · Trust 50/100

Cause

When a run errors, a polling trigger does not advance its position, so the same malformed item is fetched again each cycle and newer items queue behind it. A module that marks an input as required fails on any item that lacks it, even if nothing downstream uses its output.

Fix

Add a filter right after the trigger that requires every field later modules treat as required, so malformed items are skipped and the position advances. Remove unused modules that declare required inputs.

Apply

Filter after the trigger with Basic operators: {{1.fieldA}} Exists AND {{1.fieldB}} Exists

Affects: Make polling triggers (Google Calendar watch events, Gmail, Twilio), July to September 2026
