Hi,
i have overwritten a report on PBI Service built with a previous version of PBI Desktop with a new version modified using the latest one. Finally, I got the download option enabled and i am able to download and open the pbix file from the portal including all the new copies of the report saved with a different name. Even thought the option is also enabled for all of the copies built with the previous version of the report, when i open the pbix file in my local PC after the download i receive this error:
Error Message:
Object reference not set to an instance of an object.
Stack Trace:
System.NullReferenceException: Object reference not set to an instance of an object.
