Download artifact task is having issues and unable to download via powershell. Edited

[Neha Boora]

Hi,

I have a build plan with Build stage-1 which generates build artifacts Binaries.zip and build stages 2, 3.. 20 they all have download artifacts task to download Binaries.zip. I run this plan nightly and out of 19 stages 1 or 2 fails with error: Unable to download artifact Non required shared artifact:   If i do re-run of failed jobs, it passes. 

To resolve this issue, I am trying to add a script task to do the same job of downloading the artifacts. For that, I am utilizing Invoke-WebRequest but it gives me blank Binaries.zip file which I can't open. 

Kindly suggest a possible solution.
