In the past few days we encountered problems with imports from Google Drive.
These problems were caused by Google's auto-migration to "New Sheets".
If you have problem with your Google Drive Extractor, removing and re-adding the problematic sheet will fix the issue.
Be aware of your previous sheet configuration like "output mapping to SAPI table" or "transposition".
Contact support@keboola.com if you are not sure how to do it.
