Defined in: packages/model/src/-private/promise-many-array.ts:30

This class is returned as the result of accessing an async hasMany relationship on an instance of a Model extending from @ember-data/model.

A PromiseManyArray is an iterable proxy that allows templates to consume related ManyArrays and update once their contents are no longer pending.

In your JS code you should resolve the promise first.
