Cannot Update Dataset in the Powerbi service

[Anonymous]

I have made change to the existingreport by adding new columns. I have published the report to powerbi service. 

My scheduled refresh is failing with the above error. 

Any thought please ! 

thanks,

Hi @Anonymous 

The issue might related to the "Changed Type" step. As stated in this article Data types in Power BI Desktop. When you load data into Power BI Desktop, it will attempt to convert the data type of the source column into a data type that better supports more efficient storage, calculations, and data visualization. Then when you refresh the data, there may exists some new data which don't fit the data type and cause the issue.Please check the 'applied steps' in the query editor to find the errors.
