I tried to rename the file and sign out/in and updated to Dec 2018 and tried to get data from power bi service but still the same
I have a student account
excuse my bad english
data source from Excel
By my test, I cannot reporduce your issue with the latest version of Power BI Desktop.
Based some similar threads, sometimes this is a temporary issue.
In addition, if your size of pbix is very large, it may also cause this error.
And what type of workspace do you publish report to? Are you able to directly use "Get Data" in Power BI Service to upload the PBIX file?
Please have a test with my attachment to check if you could publish this pbix to your service.
