Unsupported source map comment

[AlCalzone]

I'm getting a ton of these when running scripts with esbuild-register:

{
  column: 21,
  file: 'C:\\Repositories\\node-zwave-js\\packages\\core\\build\\index.js',
  length: 12,
  line: 32,
  lineText: '//# sourceMappingURL=index.js.map',
  namespace: ''
}

{

  file: 'C:\\Repositories\\node-zwave-js\\packages\\core\\build\\capabilities\\CommandClasses.js',
  length: 21,
  line: 245,
  lineText: '//# sourceMappingURL=CommandClasses.js.map',
  namespace: ''
}

  namespace: ''
}

Any idea what I can do?

Getting this too, if you change sourcemap: 'both' to false in dist/node.js you can patch for now to disable sourcemaps but not get the errors.

This message seems to come from this line in esbuild:
https://github.com/evanw/esbuild/blob/c5a88a04561debf302243b0afd11d365257a2373/internal/bundler/bundler.go#L551

In my case, rebuilding the local package with "inlineSourceMap": true (in tsconfig.json) solved the problem.

See evanw/esbuild#1358 (comment) - esbuild-register uses the transformSync API which does not do path resolution. If it used the buildSync API instead it could support the external source maps.
