[1.13.6 Regression] RESTAdapter.findRecord does not accept a list of records anymore

[dschmidt]

Hey,

my server returns a list of records for findRecord requests, which used to work just fine up until 1.13.6.

E.g.:
/artist/45

{
  artists: { id: 45, name: 'Foobar' } 
}

triggers now

TypeError: Cannot read property '_internalModel' of undefined

here: https://github.com/emberjs/data/blob/master/packages/ember-data/lib/system/store/finders.js#L32

For now I worked around it like this:

   const pluralize = Ember.Inflector.inflector.pluralize.bind(Ember.Inflector.inflector);

   [...]

    findRecord(store, typeClass, id, internalModel, options) {
        return this._super(...arguments).then((response) => {
            const modelName = internalModel.modelName;
            if(!response[modelName] && response[pluralize(modelName)]) {
                response[modelName] = response[pluralize(modelName)][0];
                response[pluralize(modelName)].shift();
            }

            return response;
        });
    },

It looks like @bmac released 1.13.7. Can you try with that? Thanks.

fwiw I don't think 1.13.7 contains a fix for this bug.

Right now I cant reproduce with neither 1.13.6 nor 1.13.7. It appears it's not triggered at all by calling findRecord on the store at all, but only with side-loading individual records - which I don't remember where I triggered this the last time in my app.

Maybe #3554 this could have any effect on this?
Then I would be fine with closing this until I run into it again with 1.13.7 - or can anyone else reproduce?

I don't think #3554 should impact this. Weird 😕

I'm closing this but will happily reopen if issue can be reproduced.
