Could someone clarify why the Data Action step in our primary inbound flow is consistently returning a 400 Bad Request error, despite the payload appearing valid in the debug logs?
We are attempting to sync Genesys Cloud interaction data with our internal CRM using the custom Data Action Update_CRM_Record. This action was created to handle specific field mappings that the standard integrations do not support. The flow executes successfully up to the point of invoking this action. The error response from Genesys Cloud indicates a schema validation failure, specifically mentioning that the customer_id field is missing or malformed. However, the debug trace clearly shows the variable ${contact.customer_id} contains a valid UUID string at that moment.
The environment is Genesys Cloud EU (Frankfurt), and the flow is deployed to the Production environment. We have verified that the Data Action’s input schema matches the variable types provided by the flow. The action itself calls a private REST endpoint within our infrastructure, which returns a 200 OK when tested via Postman with the same payload structure. This suggests the issue lies within how Genesys Cloud processes the output or validates the input before sending it to our endpoint.
We have reviewed the Data Actions documentation but found no specific guidance on handling dynamic variable types in custom actions. Is there a known limitation regarding UUID handling in Data Actions? Or could this be related to the recent platform update in the EU region? The failure rate is currently 100%, which is blocking our quality assurance team from accessing updated customer context during live calls. Any insights into the internal validation logic for Data Actions would be greatly appreciated.
