Started receiving the below connection error when refreshing data from Quickbooks Online to the PowerBI service on 6/21/2021. Haven't had any issues connecting in the past and am using the standard ...
My QBO connection is using the old data tables and contains the "class" table which were somehow changed or removed from QBO and were causing the refresh error. I removed the class table from my dataset in Desktop, then re-published and refreshed without error. I don't use that table for any reporting, so it did not have an impact. Snip from my error message below identified the fields that caused my refresh errors. Hope this helps.
