Solutions

1. Use a supported driver name in gorm.Open (mysql, postgres, sqlite, sqlserver, etc.).
2. Check the driver import is present, e.g. import "gorm.io/driver/mysql".
3. Verify the Dialector passed to gorm.Open is constructed correctly.

Example fix

Open with a supported driver name: gorm.Open(mysql.Open(dsn), &gorm.Config{}) // not an unknown driver string
