Why did I need to swap $model and $relation in model relationship controller?

Hey guys, I ran into something recently that maybe someone could help me figure out.

I have Job and Task, where Job hasMany Tasks.

I added a controller like this:

<?php

namespace App\Http\Controllers\Api;

use App\Job;
use App\Task;
use Illuminate\Http\Request;
use Illuminate\Database\Eloquent\Builder as EloquentBuilder;
use Orion\Http\Controllers\Controller;

class JobTaskController extends Controller {
    protected $model = Job::class;

    protected $relation = 'tasks';

    /**
     * Builds Eloquent query for fetching entity(-ies).
     *
     * @param Request $request
     * @param array $requestedRelations
     * @return Builder
     */
    protected function buildFetchQuery(Request $request, array $requestedRelations): EloquentBuilder {
        $query = parent::buildFetchQuery($request, $requestedRelations);

        $query->whereHas('job', fn($query) => $query->where('jobs.company_id', '=', $request->user()->company_id));

        return $query;
    }

    public function exposedScopes(): array
    {
        return ['withCalculatedQuantity', 'withTotalHours', 'withTotalOvertimeHours'];
    }
}

And registered it in api.php like this:

    Orion::resource('jobs',      JobController::class);
    Orion::resource('tasks',     TaskController::class);
    Orion::hasManyResource('jobs', 'tasks', JobTaskController::class);

But I found the API responses are giving me Jobs rather than Tasks? (at this endpoint: https://96d3-216-237-193-16.ngrok-free.app/api/jobs/14170/tasks/search)

But when I switch the $model and $relation properties, like this:

    protected $model = Task::class;

    protected $relation = 'job';

... then it works?

But it doesn't seem like this is exactly the right answer either, so I'm a little bit confused. Is there anything obvious I'm messing up here?

Thank you for checking this out!

For anyone looking for the answer to this. One is supposed to extend Orion\Http\Controllers\RelationController (not Controller) for controllers associated with relations.
