I am trying to import a base from Airtable, but I got this error: “Duplicate column alias”

I have a question about importing data from Airtable. Is it possible to have detailed logs when an error occurs? I have a “Duplicate column alias” error, and I don’t have the information on which table is the problem.

End of import when you notice error, you will likely see a download button to the right. That should have additional details about the error in consideration.

The downloaded log file is the same as that in the terminal. No more information.

If I create a new table at the end of the database, the process stops at the last empty table.

Neither of your solutions is working for me.

As the error hints there can be identical columns which might be conflicting on conversion to nocodb.

See what columns can it be - column starting with underscore are a suspect if you ask me. As that underscore is probably getting lost in translation. A screenshot of your source table columns will help.
