Additional Context

[jmyersmsft]

Is there any output before the line "File is not a zip file"? If so, could you add it?

[quilter-AndrewWilde]

The only output is The command failed with an unexpected error. Here is the traceback:

[jmyersmsft]

If you add --debug to your command line, we may get more information

Before doing that, let's try clearing out any bad state by deleting %userprofile%\.azure\cli\tools\artifacttool (%userprofile% is very likely c:\users\<username>\)

(I've truncated the initial logs since they are the same between successful & failed runs, so I doubt will be much use in debugging what's causing this)

Our pipeline uses Microsoft Hosted Agents, and the VMs that run the build should be fresh each time, so there shouldn't be any differences in the machine configuration between successful and failed runs.

Late to the party but I leave this here for anyone looking for an explanation.

We encountered the same error in our corporate environment and, in our case, we tracked down the problem to Zscaler which was blocking the request to get the ArtifactTool zip file (on the log above see the line Downloading ArtifactTool from https://0psvsblobprodwus2145.vsblob.vsassets.io/artifacttool/artifacttool-win10-x64-Release_0.2.236.zip......)
