Oauth Popup Window Error - Dataflows

[nhalloran24]

I am currently using a sharpoint group to upload files into and then pull them into my PBI report. The files are csv files. Everything is able to connect and works fine in the desktop. I then go to the advanced editor and copy the query like I have done for numerous queries in the past (currently have other dataflows set up with the same file types), and then open up to create a new dataflow and paste the query in, I continue to get a message stating there was an error in the Oauth Popup window. Extremely frustrating as I am following the same process I have for other files in the past. I have tested removing the file, adding a new one to the report, changing the file name to not include any spaces, created a new Sharepoint group, nothing seems to be working. 

Anyone else having issues like this?

Also should add, I tried to upload using One Drive as well, but did not work and received the same error.

Hi @nhalloran24, 

Based on my test, if we create a dataflow entity use blank query connector, there should be a option for us to specify the SharePoint online credential. Please find this option then sign in with a valid account.
