Incident Timeline
Resolved
This incident has been resolved. We have observed that instance rates are returning to normal levels and affected connectors are syncing successfully.
Incident Summary
Description:
We identified an issue for TikTok Connectors which resulted in syncs failing with an "Invalid Parameter" error.
Timeline:
This issue began on 2026-08-31 at 14:00:00 UTC and was resolved on 2026-09-01 at 16:30 UTC.
Cause:
TikTok's Marketing API started rejecting requests that combine the country_code dimension with the billed_cost metric in GMV Max ads reports. Since all those errors were unexpected, it caused the syncs to fail.
Resolution:
Our team deployed a fix to update the code, enabling it to detect conflicts between metrics and dimensions. The connector now smoothly skips the problematic report table for each advertiser and logs a UI warning, ensuring the rest of the sync process finishes without issues.
