Error when deploying a report to Power BI Report Server October 2017

Hi guys,

so we this weird problem when trying to deploy a Power BI report from Power BI Desktop (October 2017) to Power BI Report Server after upgrading from the June release to the October release of both PBI Report Server and PBI Desktop.

The error message is the following when deploying from PBI Desktop: An error occured while attempting to save the report to Power BI Report Server

It seems we are not the only ones having this problem after looking at this forum. The thing is, after looking at the logs it seems that our problem is not the same as others are having. It seems related to the new AS "instance" that the report server is now hosting. You can see the error log that we get just after getting the error:
