object reference not set to an instance of an object

[production3]

I have a functional pbix, which I always publish it to my Power BI account via "Publish to Power BI" in File menu in the Desktop. As I was doing it just now, it gave me this error: an error while attempting to publish "xxxxx.pbix", object reference not set to an instance of an objct. 

I was able to publish the same pbix the day before. Another wield thing is, when I login my Power BI account today, all existing reports are gone, disappeared. what happended?

Please help.

thanks,

@production3,

When publish a existing report to Power BI services, you will get the waring below

In your scenario, you get an error directly when repblish a report. This issue could be cause by Power Bi services. Are you a free user or pro user? Can you get your reports in Power BI services now?
