Spectrum in Photoshop 24.2.0 not working?

Hello, total beginner here, so I know the fault is mine, but I just don’t know where to look or what to do.

Here is what I do:

  • Create a plugin from UXP Developer Tool, using the quick-layers-starter template.
  • As a test, replace the <body> content of index.html with this code.

As a result, I get this, instead of what the documentation shows.

What steps am I missing or what am I not understanding to get the same result as in the documention?

Thanks a lot.

Spectrum Web Components are not yet supported and would be coming in phases from UXP v7 onwards. For now do look at Spectrum UXP documented here - https://developer.adobe.com/photoshop/uxp/2022/uxp-api/reference-spectrum/


I see! Thank you for the quick answer!
