NPM–401 error when restoring packages from an Azure DevOps Artifacts NPM registry

I had to make some changes to an Angular application, so I cloned the app and ran ‘npm install’. This failed with the following error message:

npm WARN tar ENOENT: no such file or directory, open 'D:\Projects\CMS\Bridges.CMS.SPA\node_modules\.staging\dayjs-f8637d82\plugin\weekOfYear.d.ts'

npm WARN tar ENOENT: no such file or directory, open 'D:\Projects\CMS\Bridges.CMS.SPA\node_modules\.staging\dayjs-f8637d82\plugin\weekYear.d.ts'

npm ERR! code E401

npm ERR! Unable to authenticate, need: Bearer authorization_uri=https://login.windows.net/<guid>, Basic realm="https://pkgsprodsu3weu.app.pkgs.visualstudio.com/", TFS-Federated   

Some packages should be downloaded from our own NPM registry hosted in Azure DevOps Artifacts. As I couldn’t authenticate succesfully this resulted in a 401 error.

To solve this I first had to install the vsts-npm-auth package:

PS D:\Projects\cms\ui\CMS\Bridges.CMS.SPA> npm install -g vsts-npm-auth

C:\Users\bart\AppData\Roaming\npm\vsts-npm-auth -> C:\Users\bart\AppData\Roaming\npm\node_modules\vsts-npm-auth\bin\vsts-npm-auth.exe

+ vsts-npm-auth@0.41.0

added 1 package from 1 contributor in 1.947s

Then I could login and create the required .npmrc file by executing the following command:

PS D:\Projects\cms\ui\CMS\Bridges.CMS.SPA> vsts-npm-auth -config .npmrc

vsts-npm-auth v0.41.0.0

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

VS Code Planning mode

After the introduction of Plan mode in Visual Studio , it now also found its way into VS Code. Planning mode, or as I like to call it 'Hannibal mode', extends GitHub Copilot's Agent Mode capabilities to handle larger, multi-step coding tasks with a structured approach. Instead of jumping straight into code generation, Planning mode creates a detailed execution plan. If you want more details, have a look at my previous post . Putting plan mode into action VS Code takes a different approach compared to Visual Studio when using plan mode. Instead of a configuration setting that you can activate but have limited control over, planning is available as a separate chat mode/agent: I like this approach better than how Visual Studio does it as you have explicit control when plan mode is activated. Instead of immediately diving into execution, the plan agent creates a plan and asks some follow up questions: You can further edit the plan by clicking on ‘Open in Editor’: ...
