No idea why this is happening, the POST request from Genesys Cloud Architect is consistently returning a 422 Unprocessable Entity when attempting to create a new incident via the ServiceNow REST API for digital messaging channels. The integration was stable until the recent tenant update in eu-west-2, and while the OAuth2 token generation succeeds without issue, the payload validation on the ServiceNow side is failing specifically on the sys_created_by field mapping. The Architect flow triggers on conversation.created for the WhatsApp digital channel, and the Data Action is configured to use the service_now_rest_api integration with the endpoint https://instance.service-now.com/api/now/table/incident. The JSON body includes standard fields like short_description, description, and priority, but the error response body contains {"error":{"message":"Cannot find field sys_created_by","stack_trace":"..."}}. I have verified that the ServiceNow user associated with the OAuth client has the incident_read and incident_write roles, and the field is definitely writable in the table schema. Cross-referencing the Genesys Cloud documentation for Data Actions, it seems the webhook payload structure matches the expected format, yet the 422 persists. Interestingly, manual curl requests from the same IP range using the same token succeed, suggesting the issue might be related to how Genesys Cloud serializes the timestamp or handles the Content-Type header in the outgoing webhook. The response headers from ServiceNow indicate X-Transaction-Id: 1234567890, which doesn’t help much with debugging the serialization logic. Has anyone encountered similar schema validation errors when pushing digital channel metadata to ServiceNow via Architect? I am considering switching to a GET request to fetch the record first, but that seems inefficient for initial creation. Any insights into the specific payload transformation happening in the Genesys Cloud Data Action layer would be appreciated, as the logs only show the final 422 status without the raw request body sent to ServiceNow.
I typically get around this by validating the payload structure against the ServiceNow schema before the outbound request. The 422 error typically indicates that the JSON structure does not match the expected format for the incident table, specifically regarding required fields like caller_id or short_description.
Check if the recent tenant update changed how Genesys Cloud serializes the data. Often, nested objects need to be flattened. Use a Set Variable task to construct the JSON explicitly:
{
"short_description": "${flow.data.short_desc}",
"caller_id": {
"sys_id": "${flow.data.contact_id}"
}
}
Verify the field mappings in the ServiceNow API documentation here. Ensure sys_created_by is not included in the payload, as this is a system-generated field. Removing it usually resolves the validation error.
The main issue here is likely a mismatch in how Genesys Cloud serializes the sys_created_by field compared to what ServiceNow expects post-update. Unlike Zendesk’s simpler ticket structure, Genesys Cloud Architect requires explicit JSON mapping for nested user objects, so try adding a Data Action step to explicitly set "sys_created_by": "{{contact:email}}" before the HTTP request to bypass the schema validation error.
