In Harness trigger payload conditions, do not use the JEXL in operator; the docs call it out as unsupported in that field. Rewrite the condition with equality checks or restructure the payload so Equals suffices.

Context: From the official Harness webhook triggers reference. The docs note that the JEXL in operator is not supported in the JEXL Condition field, even though it is valid JEXL elsewhere in the platform. A trigger condition using in silently does not do what you expect, and the failure shows up as the trigger never firing rather than a syntax error.
