Hi Fivetran Support,

We encountered an issue during the recent sync where the following tables could not be written to our S3 Data Lake destination:

“We couldn’t write the following tables as their underlying files are missing in your respective cloud storage bucket.”

Affected tables:

• booking_metrics

The destination is set up using Managed Data Lake Service with AWS S3 as the storage provider. The connection itself is successful, and previous syncs were working fine. However, during this sync, the underlying Parquet files appear to be missing or not accessible, resulting in partial failure.

Could you please investigate and confirm:

• What caused these file references to be missing?

• Whether this is recoverable or requires a resync?

• Any configuration issue that may have led to this?

Please treat this as high priority, as our downstream processes rely on the availability of these files.

Thanks,
