404 - Unable to evaluate the latest vscode version

According to the official documentation here the Yeoman generator tool can generate extensions for Visual Studio Code with the help of the generator-code generator.

So i started a new project (empty folder) generated a new package.json and installed the latest yo and generator-code from npmjs.com

Then i followed the guide to create a new Color-Theme extension, but the first thing i was facing with is (maybe) a temporal error (see screenshot below)...

Seems the actual version isn't able to fetch the latest version spec from remote url https://update.code.visualstudio.com/api/releases/stable so iam unsure if this is just an temporal issue (admins doing work on those site) or is this a real bug (an outdated remote url, or so).

Now its not clear if the fallback to version ^1.54 is enough to create a full extension for actual Visual Studio Code!?

I'm running VSCodium 1.95.3

Start with the generator-code setup in the mentioned package.json and reproduce the color-theme generation from an empty folder using VSCodium 1.95.3. Check the request to https://update.code.visualstudio.com/api/releases/stable and the fallback to ^1.54; done means identifying why the latest version cannot be evaluated and confirming whether the fallback remains valid.
