Description

When using a closure in a job chain after batch jobs (as documented in the "Chains and Batches" section of the Queue documentation), the chain fails with a Call to undefined method Closure::getClosure() error.

This occurs specifically when:

1. A job chain contains one or more batches
2. A closure is placed in the chain after the batch(es)
3. The batch completes successfully
4. The ChainedBatch callback attempts to dispatch the next item (the closure)

Steps To Reproduce

Create three simple job classes with the Batchable trait:

// app/Jobs/FlushPodcastCache.php
<?php

namespace App\Jobs;

use Illuminate\Bus\Batchable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Queue\Queueable;

class FlushPodcastCache implements ShouldQueue
{
    use Queueable, Batchable;

    public function handle(): void
    {
        // Implementation
    }
}

// app/Jobs/ReleasePodcast.php
<?php

namespace App\Jobs;

use Illuminate\Bus\Batchable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Queue\Queueable;

class ReleasePodcast implements ShouldQueue
{
    use Queueable, Batchable;

    public function __construct(public int $id) {}

    public function handle(): void
    {
        // Implementation
    }
}

// app/Jobs/SendPodcastReleaseNotification.php
<?php

namespace App\Jobs;

use Illuminate\Bus\Batchable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Queue\Queueable;

class SendPodcastReleaseNotification implements ShouldQueue
{
    use Queueable, Batchable;

    public function __construct(public int $id) {}

    public function handle(): void
    {
        // Implementation
    }
}

Then dispatch a chain with batches followed by a closure:

use App\Jobs\FlushPodcastCache;
use App\Jobs\ReleasePodcast;
use App\Jobs\SendPodcastReleaseNotification;
use Illuminate\Support\Facades\Bus;
use Illuminate\Support\Facades\Log;

Bus::chain([
    new FlushPodcastCache,
    Bus::batch([
        new ReleasePodcast(1),
        new ReleasePodcast(2),
    ]),
    Bus::batch([
        new SendPodcastReleaseNotification(1),
        new SendPodcastReleaseNotification(2),
    ]),
    function() {
        Log::debug('Closure Run');
    }
])->dispatch();

Expected Behavior

The closure should execute after all batches complete successfully, as documented in the Laravel Queue documentation under "Job Chaining" which explicitly shows that closures can be mixed with job classes in chains.

Actual Behavior

The chain processes successfully through all jobs and batches, but when ChainedBatch attempts to dispatch the closure, it throws:

Call to undefined method Closure::getClosure() at /app/vendor/laravel/framework/src/Illuminate/Queue/CallQueuedClosure.php:113

Additional Context

• Closures work fine in chains when NOT following batches
• Using a job class instead of a closure works as expected
• The issue appears to be in how ChainedBatch serializes/deserializes the closure for dispatch
• This follows the exact pattern documented at https://laravel.com/docs/12.x/queues#chains-and-batches

If no one else is working on this, I'd like to investigate and try to fix this issue.

My Tuppence

I'm also having this issue - I spent a little time trying to diagnose but only got so far in the time I had.

Tests

I couldn't find the framework tests for serialising/unserialising closures in batches, the closest I found was tests/Bus/BusBatchTest.php::test_jobs_can_be_added_to_the_batch which adds a closure, but doesn't check it executes.

Some ideas

It seems that the closure is being set in the constructor:

framework/src/Illuminate/Queue/CallQueuedClosure.php

Line 53 in f04fb3a

$this->closure = $closure;

But is the null when displayName() is called.

framework/src/Illuminate/Queue/CallQueuedClosure.php

Line 113 in f04fb3a

$reflection = new ReflectionFunction($this->closure->getClosure());

I wondered if the CallQueuedClosure is being serialised, or something, and that's causing it to lose?

This is the stack trace to the __construct (in case someone can compare it with the displayName one to figure anything out.

Workaround

The only workaround I've figured is to avoid using closures, and to create a separate job class. I tried an anonymous class but Laravel doesn't support serializing them.

In the hope this is a temporary bug in Laravel, I've actually just stuck it at the bottom of my Action class which queues the jobs.

class UpdateSyncedAt implements \Illuminate\Contracts\Queue\ShouldQueue
{
    use \Illuminate\Foundation\Queue\Queueable;

    public function __construct(public string $class, public string $newSyncedAt) {}

    public function handle()
    {
        app($this->class)->updateSyncedAt($this->newSyncedAt);
    }
}
