Unable to Import Model from NPM Module in ZenStack

[ABouque]

Hi,

I'm encountering an issue when trying to import a model from an NPM package into my ZenStack project. The import works fine when using a relative path, but fails when using an NPM module. The error message explicitly states:

Cannot find model file {CORRECT PATH}

Steps to Reproduce:

1. I created a ZenStack project with workspaces and added a package containing a .zmodel file.
2. Attempted to import the model in my ZenStack schema:

   import "my-npm-package/schema.zmodel"; // Fails

3. Ran the ZenStack CLI:

   npx zenstack generate

Expected Behavior:

ZenStack should correctly resolve and use the imported model from the NPM module.

Actual Behavior:

• When using a relative path (import "../../node_modules/my-npm-package/schema.zmodel";), the import works as expected.
• When using the package (import "my-npm-package/schema.zmodel";), ZenStack throws the following error:

  Cannot find model file {CORRECT PATH}
  

  (where {CORRECT PATH} is the actual, valid path where the model exists inside node_modules).

Environment:

• ZenStack Version: 2.11.6
• Node.js Version: 20.11.0
• NPM Version: 10.2.4
• OS: Windows
• Database : Postgresql

Reproducible Example:

To make it easier to debug, I’ve created a minimal reproducible example on StackBlitz:

Additional Context:

• The package is correctly installed in node_modules through workspaces.
• Other parts of my application can correctly import it.
• The issue seems to be related to how ZenStack resolves module paths.

Any guidance or workaround would be greatly appreciated! Thanks in advance for your help.
