Description

When I use a node import inside an exported module and run the build script i get the error above.

In this example i installed and used the shoelace library "@shoelace-style/shoelace": "^2.19.1". I'm using version 1.13.2 of Framework.
I was able to reproduce the error with other packages as well. In case of our private chart library e.g. it was d3 that couldn't be found.

dynamicPaths is configured as follows:

{
  dynamicPaths: ["/chart.js"],
}

The src/chart.js has the following content:

import "@shoelace-style/shoelace/dist/components/input/input.js";
import { html } from "htl";

export function Chart() {
  return html`<sl-input label="Hello world"></sl-input>`;
}

The issue only appears when chart.js is defined as an exported module.
If i import the Chart function into a markdown file and use it there, then the build process runs successfully.

I hope this is enough information to reproduce the bug.

UPDATE:
Actually, I was able to resolve this. Turns out one of my import statements in the js file had an incorrect path. After fixing the path, this issue went away.

Thanks for posting @daenub, I'm experiencing the same issue when following the embed docs that imports npm:htl:

Unexpected error: Cannot find module 'htl@0.3.1/index.js'
Require stack:
- /Source/my_dashboard/src/noop.js

I ran npm install htl but still the same issue. I then removed the npm:htl import code and its references completely from the js file and it's still unable to build with the same error. Note there is no noop.js file either.
