Last refresh failed: We cannot convert the value "[Binary]" to type Binary..

There was an error when processing the data in the dataset.

Data source error: We cannot convert the value "[Binary]" to type Binary..

The exception was raised by the IDataReader interface.

Table: artifact. Cluster URI:

Activity ID: comeback

The reports dataset is made from SharePoint folders holding Excel files (all with identically named sheets) differently named files, obviously. They are merged, this works fine. The dataset is then merged with data from the Azure Billing API, this works fine and if I refresh the data set within Power BI desktop, no issues.


In fact, I am spending a couple hours of my day each month just refreshing the report locally so that I can upload it over and over again to the APP which is shared throughout our entire organisation.


Read through all the posts, but no workaround seems viable. Anyone have some advise or whether this bug is being resolved?

The issue seems to be the privacy settings in Power BI Service. Try the solution here
