ember Error: Assertion Failed: fullName must be a proper full name

Question

I got the following error while running a test with Ember.js:

Promise rejected before "...": Assertion Failed: fullName must be a proper full name

What is the meaning of this error?

Answer 1

You might also encounter this error if you are using the new nested subfolder angle bracket syntax: <Foo::Bar />

Make sure you have the latest version of ember-angle-bracket-invocation-polyfill, at least 1.3.0
