Error: Failed to install the MSDO CLI nuget package while running behind proxy

[mnieto]

After the update to the 1.7.x version, the MicrosoftSecurityDevOps@1 started to fail in Azure DevOps self-hosted agents configured behind a proxy
It's failling in both Windows and Linux agents. The below logs are from Windows2022 agents

In previous versions, 1.6.x ,when it had dependency on dotnet, execution was fine

I have the same problem with a self-hosted agent. After the update the task is now failing because MSDO CLI not installing

[CapgG-sleeke]

Did this problem ever progress to a workaround or even a solution ? We have upgrade just recently to v3.230.2 and now have issues with our self hosted agents on premise. Our Azure hosted agents are running a-ok.

As far as i can see the node.exe that runs index.js ( "C:\agent\externals\node16\bin\node.exe" "C:\agent_work_tasks\MicrosoftSecurityDevOps_XYZ\1.11.0\index.js") doesn't honor the proxy setup,

Testing with procmon64.exe shows that node.exe connects to the public IP's on 443 for the MicrosoftSecurityDevOps task.

Examples working with node.exe :
AzureKeyVault 1.232.0 run.js
UseDotNet 2.232.0 usedotnet.js

Not working with node.exe :
MicrosoftSecurityDevOps 1.11.0 index.js

I found a resolution for this, and posted on the github repo issue running MSDO behind the proxy

This issue actually seems to be with a dependent msdo-nuget-client.js that doesnt handle any proxy connection
