vsts-npm-auth can't get authentication token on VSTS build

I'm attempting to use vsts-npm-auth to get the authentication token for our VSTS package repository. On my development machine I can run the commands

npm install -g vsts-npm-auth vsts-npm-auth -config path-to-my\.npmrc

and it succeeds in providing me with an authentication token. I'm now trying to recreate this as a build step on VSTS, so I create the powershell script auth-vsts.ps1

$npmrcFile = "$PSScriptRoot\path-to-my\.npmrc";
npm install -g vsts-npm-auth;
vsts-npm-auth -config $npmrcFile;

and add it as a powershell task. However, the task fails as follows

The error gives no indication as to why it can't obtain the credentials. Any ideas why this might be?

I faced this issue while trying to execute via Visual Studio Code`s powershell terminal

vsts-npm-auth -config .npmrc

But running the same command via simple console solved this issue and I was redirected to authentication window.

Can suggest that due to internal limitations powershell disabled to open another windows.

This worked for me

npx vsts-npm-auth -config .npmrc

The vsts authentication system sometimes authenticates the use by popping up a browser window. If the terminal you're running the command from is not interactive (e.g., ssh terminal, vscode terminal) it won't be able to pop up that window, and the authentication will fail.
