@Anonymous, take a look at this post: https://community.powerbi.com/t5/Service/PowerBI-dataset-refresh-error/m-p/1490877#M113467

You'll need to upgrade to the latest version of the gateway.

Hi @Anonymous 

Based on the error it cannot find the step in PowerQuery that refers to "List.ConformToPageReader matches no exports. Did you miss a module reference?"

If you can please refresh in Power BI Desktop and then re-upload the file?
