Power BI Report server - Issue with deploying power bi report

Hi Guys,

I recently installed a PBIRS Instance (CTP) and SQL 2017 on the same virtual machine in order to try out the new PBIRS and create/deploy some sample PBIX reports to this on-prem PBI server. I'm running into the same problem as rest of the people here. Everytime I create a PBIX report using the June 2017 version of PBI Desktop and try to deploy to on-prem PBIRS instance, I am presented with a very generic error message. When I dig in to the RS log files, this is what I see:-

Is there a patch for PBIRS I can download in order to fix this issue? I read through the responses from Msft team here in this thread and I concluded that they have a patch to fix this without me having to change some settings/service accounts on the server?
