Hi,
i have overwritten a report on PBI Service built with a previous version of the PBI Desktop with a new version modified with the latest version of the application. After that, I got the download option enabled and can download and open the pbix file downloaded from the portal and for all new copies of that (save as). But, event thought the option is enabled for previous saved copies of the report when i open the pbix of that 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.
