Azure Cost Management - Error - We cannot convert a value of type Binary to type Function

Hey,

Since the beginning of September, our refresh of the data extracted from the Azure Billing via the Azure Cost Management Connector is failing through the Power BI Services online. (has been working for over a year) Refreshing data from the Power BI application on my workstation does succeed. It's unclear as to why it suddenly stopped working nor can I find a resolution.

Error during refresh :

Findings : 

When I try to update the references for the Azure Cost Management connector, I receive an error during log in.

I assume the login is causing the error, but I do not know why.

Thanks in advance for some assistance!
