Hey @nelak2, thanks for the bug report!

I looked into this during the last few weeks and found out that the problem likely has to do with a TypeScript versioning mismatch between what Angular v15 uses and what FAST uses (a technology we use to build the toolkit components).

See more of that discussion here.

It means that a fix for using the toolkit in Angular v15 might, unfortunately, take a while. In the meantime, however, I just merged a PR that (among other things) reverts the angular-hello-world sample back to using Angular v13.

I will keep this issue open as a reminder to adopt a fix from FAST whenever it is released.

Hi @nelak2!

Back with a final update: I'm very sorry to say that the toolkit is being deprecated and all development on these samples has come to a close.

There was an announcement earlier this week on the main toolkit repo where you can learn more details and leave any questions or comments you may have.

Beyond that, thank you so much filing this issue and apologies for never getting around to addressing it. It means a lot that you contributed to the improvement of this project. I wish you all the best in your future VS Code extension endeavors!
