Seems related to node-gyp v3.8.0 dependency of node-sass (<5) what supports only python2 (EOL)
sass/node-sass#3013
sass/node-sass#2877
Also interesting Libsaas and Node-Saas are deprecated. Not better to switch to sass as recommended?

managed to run it with dart-saas https://github.com/sass/dart-sass/releases/tag/1.32.4

Thanks for the pull request @ChristianBeier. I was stumbling across the same problem.

In the package.json change this:
"node-sass": "^4.14.1", --> "sass": "^1.32.4",

This fix is now in the development branch. Once we've finished our test pass, it'll be merged into master. Thanks!

Closing as the fix is now in the new default main branch here: https://github.com/Azure-Samples/digital-twins-explorer

Thanks again for reporting!
