Hey @Victor_Melara, the list mismatch issue you’re seeing is happening because the data you’re passing in doesn’t have a one-to-one match between list items. That makes it troublesome for the node to properly update each row.
The easiest fix is to remove the error shields around specific nodes. I’d recommend removing the error shield from the Facebook Ad Scraper and the Get List Item nodes. Then, create a subflow that includes everything downstream of the Google Sheet Reader node – that means the Facebook Ad Scraper, Get List Item, and Sheet Updater nodes. You can then loop this subflow over your Sheet Reader node, and just add an error shield around the entire subflow instead of each individual node.
Here’s the documentation on list size mismatches with more details and examples.
Let me know if anything’s still unclear or if you run into more issues. Happy to help.
