Does anyone know why a custom Data Action configured to trigger immediately after a WFM schedule publication is consistently failing with a 400 Bad Request? We are trying to push updated agent availability states to an external workforce optimization dashboard via a REST API call, but the payload construction seems to break down during high-volume publication windows.
The flow is set up in Architect to listen for the ‘WFM Schedule Published’ event. It grabs the schedule data, maps it to our custom JSON schema, and sends a POST request to our internal endpoint. This works perfectly for small team publications. However, when we publish the full contact center schedule (approx. 250 agents) on Tuesday mornings, the Data Action fails.
The error log in the Data Action execution history shows:
“Action failed: HTTP 400. Body: {"error": "Invalid JSON payload. Expected array at root level, got object."}”
I have verified the JSON structure in the test environment, and it is valid. The issue appears to be related to how the WFM event payload is being transformed when the dataset exceeds a certain size or complexity. The transformation block uses a simple loop to iterate over the agents array within the schedule object.
Environment Details:
- Genesys Cloud Release: 2024-03 (Patch 2)
- Timezone: America/Chicago
- Integration Type: Custom Data Action (REST POST)
- Payload Size: ~45KB when failing
Is there a known limitation on the payload size or complexity for Data Actions triggered by WFM events? Or is there a specific way to handle large schedule objects to prevent JSON parsing errors downstream? We need this integration to be reliable for our real-time adherence tracking. Any insights on handling large WFM data payloads in Architect would be appreciated.
