Troubleshooting SQL Query Issues with Dust Database Errors

Hello! Since a few days I got an error each time my assistant use the query table. I seems that it cannot find the right database name to select the data from. Nor it using the wrong database name or throw an error Error running TablesQuery app Is there anything on Dust side that might justify this issue (that I did not have at all last week) on any tips on making sure the SQL request is the right one?
