I'm using the Salesforce Object Connector, but receive the following error message when loading the data:
DataSource.Error: Query is either selecting too many fields or the filter conditions are too complicated. Details: List
I won't need all columns from the object so I want to reduce the number of columns selected. I understand how to do this once the connection is established, but given the above error I dont have the option. The Choose Coulmns button is grayed out.
