Ember multi word model name - The response from a findAll must be an Array, not undefined

Question

My model is var UserLookup = DS.Model.extend({ 'name': DS.attr('string') });
In My adapter I lookup as follows this.store.find('userLookup').then(function(results){ }
The response from REST API is {"userLookups":[{"id":1,"name":"xxx"},{"id":2,"name":"yyyy"}]}

Upon deserialization it fails with error Error: Assertion Failed: The response from a findAll must be an Array, not undefined

I made sure the model lookup and the key in JSON response are both camelCased. If I rename the model with a single word, everything works.

Am I missing something in serializer that could cause this error?

Did you register the model on your application variable, i.e. App.UserLookup = ...? Because I don't think it's going to work if you register it as a global. — yorbro

I return the model from the router and this works if I rename the model to a single word. The problem arises only in case of models with multi word names. — Narayanan Nachiappan

Have you tried returning { "user_lookups": [...] } as JSON, i.e. use snake case instead of camel case? — yorbro

Are you using the Rest or ActiveModel serializer? If so, can you try debugging github.com/emberjs/data/blob/master/packages/ember-data/lib/… to see what type ED is trying to lookup for your "userLookups" key? — IgorT

I believe the root key in the API response needs to user_lookups, not userLookups
