Fivetran: The Trade Desk connections are failing because of multiple errors

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 The Trade Desk connectors, which resulted in syncs failing with one of three errors:
1) 429 Rate limiting
2) NumberFormatException - failure while processing Excel reports containing text values in cells formatted as numbers
3) ReportFilter Empty Filters Error - failure when report filters are configured without advertiser or partner IDs


Timeline:
This issue began on January 29 at 1:04 UTC and was resolved on January 30 at 20:46 UTC.

Cause:
We are still determining the root cause and will update when we know more.

Resolution:
The 429 Rate Limiting error resolved on its own. Fivetran deployed changes to handle the remaining two errors.

The fix for the issue causing some syncs to fail when report filters were configured without advertiser or partner IDs has been deployed. We’re observing a steady decrease in failure rates and will continue to monitor sync performance closely.

For the error - "Some syncs are still failing when report filters are configured without advertiser or partner IDs." - a fix to skip reports with empty filters is currently under review.

We identified the following issues affecting the Trade Desk syncs:

1)Syncs failed due to rate limiting from The Trade Desk API and have since recovered automatically.
2)Syncs failed while processing Excel reports containing text values in cells formatted as numbers and have since recovered automatically.
3)Some syncs are still failing when report filters are configured without advertiser or partner IDs.

We are continuing to investigate the remaining failures.

The issue has been identified and we are working to resolve it.
