Hello There, We encountered the following error while attempting to load the data and are unable to identify the columns referenced in the error. Any guidance on how to identify those unused columns? Error processing taskId status=ERROR message="Non-synchronized dataset "dataset.test/18802", identified unused columns "27055,27170,27018,27168,27053,27902,27020,27900"." ETL PULL ERROR.

Hi Geetha, I see that you have also opened a ticket with our support team. We have followed up in that thread, but since this is public facing I will paste the general fix: Please execute the SYNCHRONIZE command as navigated here. This should fix the issue. Note that if the error persists, you may need to run it without the PRESERVE DATA, i.e., the changes introduced by it will be destructive and you will need to reload all the data to the dataset.
