- Why does this setting in the custom Data Action configuration cause the platform to reject valid JSON payloads when updating a third-party CRM record via the integration endpoint?
- The integration is built using the AppFoundry framework for a mid-sized enterprise client operating in the US East region. The primary goal is to synchronize call disposition data from Genesys Cloud to a legacy Salesforce instance using a custom Apex endpoint.
- The specific issue arises within the Architect flow when the ‘Update Record’ Data Action is triggered. The payload construction appears correct based on the debug logs, yet the platform consistently returns a 400 Bad Request error.
- The error response body from Genesys Cloud indicates a validation failure on the ‘externalId’ field, stating that the format is invalid, even though the value matches the UUID format required by the Salesforce API documentation.
- Investigation reveals that the Data Action is configured to use OAuth 2.0 for authentication, and the access token retrieval is successful without any latency issues. The timeout settings are set to the default 30 seconds, which should be sufficient for this operation.
- The payload being sent includes nested objects for the ‘customFields’ array, which contains sensitive PII data that is masked in the logs. The schema validation on the Genesys Cloud side seems to be overly strict regarding the structure of these nested arrays.
- Attempts to simplify the payload by removing the ‘customFields’ array result in a successful update, confirming that the issue is related to the complexity or structure of the additional fields being passed.
- The integration uses the latest version of the AppFoundry SDK, and all dependencies are up to date. No recent changes were made to the Salesforce endpoint or the Genesys Cloud organization settings.
- The error occurs intermittently, affecting approximately 15% of the update requests, which makes debugging challenging as the same payload may succeed in one instance and fail in the next.
- Reviewing the API rate limits shows no throttling events, and the request volume is well within the allocated limits for the client’s subscription tier.
- The question is whether there is a known limitation or specific configuration requirement for handling complex nested JSON structures in the ‘Update Record’ Data Action that is not documented in the current developer guide.
- Any insights into the internal validation logic for this Data Action or recommendations for restructuring the payload to avoid the 400 error would be greatly appreciated.
