Note: The steps below are intended to help identify and resolve the issue. If the error is still present after working through the steps, follow Step 5 to gather some information and reach out to SAP Signavio Support for further assistance.

1. Go to the Connections within the Process Data Pipeline.
2. Find the relevant source connection and select Test Connection.
   • If the test fails, the issue is likely with the connection configuration — continue to Step 3.
   • If the test passes, skip to Step 4.
3. Check the source connection configuration for the following common issues:
   • Credentials that may have expired or been recently changed
   • An RFC destination that has been updated or is no longer valid
   • Any mandatory connection fields that are empty or incomplete
     Once any issues have been corrected, re-run the connection test to confirm everything is working.
4. Open the relevant source data entry and check that all required fields are filled in and correctly configured.
5. If the error is still appearing after completing Steps 1–4, please gather the following and send it to SAP Signavio Support:
   • A HAR browser log, which can be exported by following the instructions in SAP Note 3464682.
   • A screenshot of the error details from your browser’s DevTools Network tab, taken while the error is visible on the Source Data tab.
