Hi everyone,
I’m completely stuck due to an error :
I don’t understand why, because in data management, this source is “Functional” and shows no errors. The Sheets file is clean, there are no duplicate headers, I have access to the file, etc. I tried to create multiple kinds of charts, with all available columns too…
I’ve tried deleting and reconnecting several times, even using the URL, but the error always returns.
All other sources work for this report !
If anyone has an answer, I would be very grateful. Thank you.
