expected value of type undefined during 'init', but received: [object Object]

[allthesignals]

I'm using mirage for testing, and I have type validation on one of my models. When I run a test, I'm seeing this:

_default#proposedGeometry expected value of type undefined during 'init', but received: [object Object]

But I have defined the type as something:

import { FeatureCollection, EmptyFeatureCollection } from './project';

// ... class {

  @type(FeatureCollection)
  @attr({ defaultValue: () => EmptyFeatureCollection })
  proposedGeometry;

The problem is that FeatureCollection actually imports as undefined in my test environment. Could this have something to do with e-decorators stripping out type validation in the wrong place?

I moved this validation over to the model that was needing it (it should go there anyways), and it seems to work fine. So I'm not sure what's happening. The validation is exported as this:

export const FeatureCollection = shapeOf({
  type: oneOf('FeatureCollection'),
  features: arrayOf(
    Feature,
  ),
});

Maybe I am doing the module syntax wrong IDK

In production environments all of the type definition helpers are removed from the final build, so you may be importing undefined because of that. However, @type should also be removed, so it's strange that you're still running into the validation issues.

We've been working on a rewrite for v1.0.0, we can definitely try to address this in the rewrite. Unsure if I'll have time to go back to earlier versions and figure out what's going on.

Hmmm. Yeah, I'm not sure. It seems to only come through as undefined when it's being exported and reimported somewhere else.

Happy to help if I can be pointed in the right direction.

Thanks!
