Angular i18n issue - Cannot read property 'toLowerCase' of null

After following the steps in the Angular documentation to setup internationalization(i18n) support, I tried to execute my brand new i18n npm command:

PS C:\Projects\test\AngularLocalization\angularlocal> npm run i18n

> angularlocal@0.0.0 i18n C:\Projects\test\AngularLocalization\angularlocal

> ng-xi18n

TypeError: Cannot read property 'toLowerCase' of null

Whoops! This was not the output I was hoping for…

Strange! Because it worked perfectly before Confused smile. A search through the issues on GitHub brought me to the following issue: https://github.com/angular/angular/issues/16235

The issue seems to have appeared in Angular 4.0.3. Luckily a workaround exists, I altered the commando in my package.json to include the prefered format:

When I invoked the i18n command again, this time it worked without a problem.

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’: ...
