The Report Action menu is not working after upgrade sql server 2008 r2 to sql server 2012 sp3

A “Message from webpage” popup with message “An error has occurred with the data fetch. Please refresh the page and retry.” (The message reappear a couple of times then clicking ok button. )

ReportingServices is running in integrated mode with sharepoint 2010 sp2

Sharepoint.avantra.se is configured as an alternate mapping and is protected by ADFS2 authentication.

Fiddler show one POST whit status 200 that return “eThere was an error in the callback.”. This is the only Fiddler entry after a click on the “Action” menu item.

Can’t find any relevant logging entry in ULSViewer.

Lots of entry then doing Sql profile. Hard to find any relevant row.

Tried to debug javascript call, but the code that populate the menu is complex and seems to be done in an Ajax asynchronous call.

Any suggestions?
