I see that you are trying to connect to arctic ice dataset from data.world through web connector.
I have replicated the same steps of connecting to any dataset from data.world and I could load data without any problem.
Please retry and let us know if you are facing the same issue again.
Hello Chatchai Chattirak,
It appears, based on the screenshot on the right hand side you've provided, that you simply need to change the data type from ABC to Date. Click on the ABC icon that field/column.
The field name is Date, but the field type is not being recognized by Tableau as Date.
Hope that helps, Don
