1. Issue Summary

   • The error CELLEXPERT_REQUEST_VALIDATION_ERROR with error code RVR-CER-303 is related to the CellExpert data connector in Data Integration. This indicates a problem with validating a request made to the CellExpert service. Initial diagnosis suggests that the issue may stem from invalid parameters or configurations being sent in the request, possibly due to incorrect formatting or missing required fields in the API call.

   • Test the Connection: Use the "Test Connection" feature in Data Integration to check if the API connection is successful without sending the actual request.
   • Review Logs: Check any logs available in Data Integration or the API service for more specific error messages that might point towards the cause of the validation failure.
   • Authentication Parameters: If the API requires OAuth2.0 or tokens for authentication, ensure these are correctly generated and included with the request.
