Relations on custom resource not working

envolutions

I have a problem where I'm not able to access relations I have made on my resource. I made a resource called tag-submissions and one submission is related to a single tag and user. If I then try to access the relation, making sure I include submissions.user when getting the tag:

app.store.find('tags', this.attrs.tag_id, { include: ['submissions', 'submissions.user'] }).then(tag => {
     this.tagModel = tag;
})

and then do:

this.submissions = this.attrs.tagModel.submissions();

console.log(this.submissions[0].user())

It logs the following:

ƒ (){const e=this.data.relationships?.[t]?.data;if(e&&e instanceof Array)throw new Error(`Relationship ${t} on model ${this.data.type} is plural, so the hasOne method cannot be used to access it.`);ret…

Even tho, it should log the user object. I'm wondering how I can fix this. I will also send all the relations I have defined:
In the front-end model:

user() {
        return Model.hasOne<User>('user');
}

The back-end resource:

Schema\Relationship\ToOne::make('user')
                ->type('users')
                ->includable(),

And the back-end model:

public function user(): BelongsTo
{
    return $this->belongsTo(User::class);
}

Lastly the database has a submission with a valid user_id and logging just this.submissions in the front end shows the user relation just not included.

The error seems to imply that the js model definition type users cannot be used on a hasOne relation, which doesn't make sense.

Still investigating.

The problem has been resolved. The issue was that the font end model definition was missing .call(this):

user() {
   return Model.hasOne<User>('user').call(this);
}
