It looks like you are creating a MySQLi connection, but then trying to create a standard Recordset. You need to create a MySQLi recordset in order to use a MySQLi connection. DataBridge doesn't work with MySQLi yet, but you can use the server behaviors directly to replicate the same functionality. You just have to use the option Webassist->MySQLi->MySQLi Recordset instead of the old Recordset option.
