PowerBI - Unable to connect error

I'm trying to setup the PowerBi connection, i have followed the instructions on Github, installed Microsoft Open R 4.0.2, installed the following packages httr and readxl. Copied the PowerBIDataSource_Report.R script and editted with our instance and API key however when trying to connect to the data source in PowerBI i get the error:

 

I'm not a PowerBI expert but if anyone has any ideas that would be great
