Can anyone clarify why my Architect flow triggers a 422 Unprocessable Entity when invoking a Data Action to ServiceNow /api/now/table/incident from a Digital Channel webhook? Genesys Cloud 2024-02.0, ServiceNow Washington DC. The payload validates in Postman but fails in the flow with ‘Invalid value for short_description’. Cross-referencing docs shows no field mapping errors. Is this a known limitation with JSON serialization in digital channel triggers?
