Some scripts fail in PS7

When running with PS7 in QA env controllservices.ps1 fails with following error (deployment ID - 1816135):
"[ERR] [PS] ErrorId: Microsoft.PowerShell.Commands.WriteErrorException,Get-DorcToken
Exception: Microsoft.PowerShell.Commands.WriteErrorException: Failed to retrieve token. Please check DorcIDSsecret variable value! Error: Unable to cast object of type 'System.Management.Automation.PSDataCollection1[System.Management.Automation.ProgressRecord]' to type 'System.Management.Automation.PSDataCollection1[System.Management.Automation.InformationRecord]'."

Based on my investigation the cause of the issue is following :
Wrong event wiring in DOrc.Cmd/dorc/src/Dorc.PowerShell/PowerShellScriptRunner.cs: Progress stream is subscribed to the Information handler.
Specifically line 61: powerShell.Streams.Progress.DataAdded += Powershell_Information_DataAdded;
