Describe the bug
When trying to run nx g @nxext/stencil:lib my-lib in a fresh Nx workspace, the target errors:

❯ ./node_modules/.bin/nx g @nxext/stencil:lib my-lib --verbose

 NX  Generating @nxext/stencil:library

✔ Which stylesheet format would you like to use? · css

 NX   Cannot convert undefined or null to object


TypeError: Cannot convert undefined or null to object

To Reproduce
Follow the directions provided in the package:

Add this plugin to an Nx workspace

Then continue to follow the directions provided in the package:

Generate your projects

This second step will fail as above.

Expected behavior
The tool generates the project without errors.

Additional context
It’s clear that “add this plugin to an Nx workspace” is not specific enough – is there an example Nx workspace available in which this command is demonstrated to work? Has this only been tested in certain engine versions?

This happens when the path key is missing in the tsconfig.base.json. Adding it manually seems to resolve the issue.

"compilerOptions: {
  ...
  "path": {}
}
