Funny thing is when I publish it to online version. Online version works
When I open pbix in desktop and use continue instead of validate , my report will appear , but It shows same error, when I use refresh.
From the message when you refresh, it seems that you use DirectQuery connection, while there have some steps require Import mode.
1. Before install the April desktop version, is the report can be refreshed successfully in desktop.
2. Is the .pbix changed after update the desktop version.
3. Open the Query Editor and check which steps used in the query cause the issue. You can open the Advanced Editor for each query and copy to save the Power Query in NotePad. Then go to Applied Steps, delete each step then apply the change to see if the error throws out.
As the issue is gone, would you please share the solution which can benefit other communities who has the same issue? Also please mark a helpful reply as an answer so that we can close the thread.
