error in addAfterCall not present

[Floriferous]

Errors in addAfterCall don't seem to be passed through properly. I see this in the browser console, but it is not passed through to addAfterCall:

Error

Here's a simple example of the setup:

const myMethod = new Mutation({name: 'myMethod', params: {} })

myMethod.setHandler(() => {
  throw new Meteor.Error('dude', 'what');
});

myMethod.run({})

Mutation.addAfterCall(({ error }) => {
  console.log(error) // undefined
})
