laravel-mongodb: Job Batching not Working

• Laravel-mongodb Version: v3.8.1
• PHP Version: 7.4.9
• Laravel Version: v8.15.0
• Database Driver & Version: jenssegers/mongodb v3.8.1

Description:

Trying to get property ‘id’ of non-object on vendor/laravel/framework/src/Illuminate/Bus/DatabaseBatchRepository.php:256

Steps to reproduce

1. Just create the Bus like:

use App\Jobs\ProcessPodcast;
use App\Podcast;
use Illuminate\Bus\Batch;
use Illuminate\Support\Facades\Bus;
use Throwable;

$batch = Bus::batch([
    new ProcessPodcast(Podcast::find(1)),
    new ProcessPodcast(Podcast::find(2)),
    new ProcessPodcast(Podcast::find(3)),
    new ProcessPodcast(Podcast::find(4)),
    new ProcessPodcast(Podcast::find(5)),
])->then(function (Batch $batch) {
    // All jobs completed successfully...
})->catch(function (Batch $batch, Throwable $e) {
    // First batch job failure detected...
})->finally(function (Batch $batch) {
    // The batch has finished executing...
})->dispatch();

Expected behaviour

in Illuminate\Bus\DatabaseBatchRepository::find

$batch = $this->connection->table($this->table)
                            ->where('id', $batchId)
                            ->first();
// $batch should be a object instead of array
if ($batch) {
// the error is trigger by this method "toBatch"
    return $this->toBatch($batch);
}

    protected function toBatch($batch)
    {
        return $this->factory->make(
            $this,
            $batch->id, // this $batch is a array and not a object
            $batch->name,
            (int) $batch->total_jobs,
            (int) $batch->pending_jobs,
            (int) $batch->failed_jobs,
            json_decode($batch->failed_job_ids, true),
            unserialize($batch->options),
            CarbonImmutable::createFromTimestamp($batch->created_at),
            $batch->cancelled_at ? CarbonImmutable::createFromTimestamp($batch->cancelled_at) : $batch->cancelled_at,
            $batch->finished_at ? CarbonImmutable::createFromTimestamp($batch->finished_at) : $batch->finished_at
        );
    }

Actual behaviour

in Illuminate\Bus\DatabaseBatchRepository::find

$batch = $this->connection->table($this->table)
                            ->where('id', $batchId)
                            ->first();
// it returns a array and not a object
