error value 'preferred'
when i try to refresh data or create a new dashboard
Expression.Error: Valur "Preferred" is not on of the correct type.
i did a test with a mysql database with only one simple table and I saw the same message error
Dear Ross73312, thanks a lot.
After playing and reviewing everything, I uninstalled the odbc connector from mysql and also uninstalled the powerbi desktop. Install everything from scratch on my laptop and it was fixed.

If i had to guess, i'm expecting your Preferred column is either of type Date or Number. You might have a step that is trying to set this column as a type such as that. In your new data, some value is appearing that is not of that type. For example if you was numbers, you might have a value that contains a dash, or a blank.

Hello! I have also the same problem! Did you change anything in your database? You had errors in data types? I am still trying to figure out what's going on. I uninstalled and installed Power BI and ODBC Connector but nothing has changed!
