# 550035: Sync canceled

Log Type: TWILIO

Log Level: WARNING

## Description

The sync operation was canceled before it finished. This can happen if a user or automated process explicitly stops the operation, or if the system ends an in-progress sync as part of resource management or conflict-resolution tasks.

### Possible causes

* A user manually canceled the sync from the Twilio Console or by calling the REST API.
* The source or dataset was deactivated while a sync was running, which stopped the active job.
* A new sync started for the same dataset, and the system canceled the existing job to avoid conflicting operations.
* A system-level event (for example, a configuration update or account-level action) required the service to stop active syncs.

### Possible solutions

* If the cancellation was unintentional, confirm that no automated processes or scripts are invoking the Cancel Sync API for this dataset.
* Verify that both the source and the dataset are active before you start a sync.
* If the sync was canceled because of a conflict, wait for any in-progress operations to finish before you trigger a new sync.
* After you resolve the underlying issue, start a new sync from the Twilio Console to synchronize any data that was missed.
