Upgrade OS11: two major issues whilst publishing first solution
Application Type
Traditional Web, Mobile, Reactive, Service
Service Studio Version
11.10.0 (Build 34712)
Platform Version
11.10.0 (Build 22422)

After platform upgrade from 10 to 11 whe are trying to upgrade the applications to version 11 by creating a solution and publishing it.

We get 2 major errors whilst publishing, for all extensions.

1: Internal Error: Could not find file 'C:\Windows\TEMP\#####.xml'.

This error we receive for both forge as custom extensions.

It looks like Outsystems is not able to write to the temp?
Can this be, and were is this managed?

2:  Error in Verify and Save: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> ssServiceCenter.ExcptIntegrationStudio: Invalid username or password.

This error we receive for all custom extensions having entities mapped to an external database.

Here it seems that whilst publishing the entities cannot be checked as Outsystems is unable to login to integration studio.

For both errors, I've no idea were to start. Any help is highly apreciated.
