So, how do you access your db without doing “SQL-related stuff”? Maybe, try to delete your .data of your project if not already done. If the previous configuration of the CSV data node is still in the .data, it might cause some errors.
I don’t see why you would get an “ODBC driver missing” error if you don’t use SQL in Taipy.
If the deletion of your .data doesn’t help, you can maybe contact me by mail to send me a copy of your code reproducing the error or organize a call.
