Core Connector Background Check Outbound: TransformBGData ApplyETV Error
The error An unexpected error occurred while processing background event BACKGROUND_CHECK_EVENT-3-6632
An unexpected error with code : -1, has occured at : TransformBGData.request.1.applyETV. Please reference message detail for more information.
What it means
The Background Check Order Outbound core connector failed partway through its internal data transform step (TransformBGData) while applying an effective-to-value to a background check event. Workday could not process that specific event and stopped with a generic internal error code instead of a descriptive one.
Troubleshooting
- Open the integration's error notification or the run's message log and note the exact background check event ID referenced in the error (BACKGROUND_CHECK_EVENT-#).
- Check the worker's background check status and history for that event; look for an event that was cancelled, superseded, or has an unusual effective date.
- Compare a working run against the failing one to see if a specific candidate or event triggered the -1 code.
- If the event looks clean on the Workday side, capture the full error detail (not just the summary line) and open a Workday Support case referencing the TransformBGData.request.1.applyETV step, since this is an internal transform failure Workday needs to diagnose.
⚡ Quick fix
Exclude or manually process the specific background check event that triggers the error so the rest of the outbound batch can complete, then rerun the connector.
✓ Permanent fix
Log a Workday Support case with the event ID and full error detail; this is a known internal transform issue that Workday resolves case by case rather than something fixable purely through integration configuration.
