WEM Data Action 400: Invalid JSON structure at path $.assignment.schedule

“error”: “Invalid JSON structure at path $.assignment.schedule”

The Data Action fails when pushing WEM assignment metadata to ServiceNow via REST API. The payload structure matches the documented schema, but ServiceNow rejects the nested array format.

schedule:
 - day: 1
 start: 09:00
 end: 17:00

Is the Data Action stripping the array brackets before sending to the SNOW endpoint?
