Quick question about why our Architect Data Action integration is returning a 400 Bad Request with error code INVALID_PAYLOAD_STRUCTURE when sending a deeply nested JSON object to our external endpoint via the /api/v2/integrations/rest endpoint. The payload validates perfectly in Postman using the same OAuth token and headers, yet Genesys rejects it during the flow execution, specifically failing on the transformation step where we map the custom disposition codes to the nested array. The SDK version is 2023-10-15 and the error trace points to a schema mismatch in the request body, but our schema definition in the integration profile matches the external API requirements exactly. Any ideas on how to debug the payload transformation within the Architect flow itself?
The root of the issue is likely the payload size hitting the Architect transformation limit rather than a schema issue. Try flattening the nested array in the data action config before sending it to the external endpoint.
TL;DR: Flatten before export.
I usually solve this by pre-processing the nested arrays in a JavaScript step to ensure the payload structure matches the strict schema expected by the legal hold bulk export API, which rejects deep nesting for chain of custody integrity.
You need to ensure the nested JSON is properly escaped within the Genesys Cloud Data Action configuration. The platform often misinterprets raw curly braces in the transformation step. Try using the jsonencode function or a dedicated JSON formatting block before the HTTP request.
Note: Verify the Content-Type header is explicitly set to application/json.
