Job failing with: Error: Call to a member function prepare()

[pgartin]

I have a particular job failing with the following error around 50% of the time:

Error: Call to a member function prepare() on null in /home/forge/landlord.swof.com/vendor/laravel/framework/src/Illuminate/Database/Connection.php:368

This Job is being dispatched in a batch within another job. This is where the job is dispatched. (The job is in the $fieldJobs array):

Bus::chain([
                $farmJob,
                function () use ($fieldJobs) {
                    Bus::batch($fieldJobs)->dispatch();
                },
            ])->dispatch();

Here is the job that is failing:

<?php

namespace App\Jobs;

...

class SendFieldToEcoProducer implements ShouldQueue
{
    use Batchable, Dispatchable, InteractsWithQueue, Queueable;
    use EcoLogin;

    protected Field $field;
    protected User $user;

    public $timeout = 60 * 3;
    public $tries = 1;

    /**
     * Create a new job instance.
     *
     * @param \App\Models\Field $field
     * @param \App\Models\User $user
     */
    public function __construct(Field $field, User $user)
    {
        $this->field = $field;
        $this->user = $user;
    }

    /**
     * Execute the job.
     *
     * @return void
     * @throws \Exception
     */
    public function handle()
    {
        if (!Tenant::checkCurrent()) {
            throw new \Exception("No Tenant Recognized");
        }

           ...

     }
}

Here is my mulitenancy.php file:

return [
    'tenant_finder' => \Spatie\Multitenancy\TenantFinder\DomainTenantFinder::class,
    'tenant_artisan_search_fields' => [
        'id',
    ],
    'switch_tenant_tasks' => [
        \App\Multitenancy\Tasks\SwitchTenantDatabaseTask::class,
        \Spatie\Multitenancy\Tasks\PrefixCacheTask::class,
    ],
    'tenant_model' => \Spatie\Multitenancy\Models\Tenant::class,
    'queues_are_tenant_aware_by_default' => true,
    'tenant_database_connection_name' => 'tenant',
    'landlord_database_connection_name' => 'landlord',
    'current_tenant_container_key' => 'currentTenant',
    'actions' => [
        'make_tenant_current_action' => MakeTenantCurrentAction::class,
        'forget_current_tenant_action' => ForgetCurrentTenantAction::class,
        'make_queue_tenant_aware_action' => MakeQueueTenantAwareAction::class,
        'migrate_tenant' => MigrateTenantAction::class,
    ],
    'queueable_to_job' => [
        SendQueuedMailable::class => 'mailable',
        SendQueuedNotifications::class => 'notification',
        CallQueuedListener::class => 'class',
        BroadcastEvent::class => 'event',
    ],

And here is some relevant env variables which I have confirmed are what are used in the config:

CACHE_DRIVER=redis
QUEUE_CONNECTION=redis
SESSION_DRIVER=redis
SESSION_LIFETIME=120

Thanks in advance for taking a look at this. Let me know if you need other specific information.

Best,

What's the command that dispatches your job?

[pgartin]

The job is add to the $fieldJobs array:

$fieldJobs[] = SendFieldToEcoProducer($field, $user)

And those jobs are dispatched in a batch here:

Bus::chain([ $farmJob, function () use ($fieldJobs) { Bus::batch($fieldJobs)->dispatch(); }, ])->dispatch();

Thanks for taking a look.

I also have the same problem.
I temporarily fixed it by changing connection to landlord in config -> queue -> batching

It working. @pgartin

[dirkam]

@minhtamwebmaster is this that you ended up with, or did you manage to make it work with the tenant database connection?

[ChristiaanBilthof]

Experiencing the same problem. Any ideas?

[kristaps777]

Any leads for this problem?
It seems I am in a similar situation.
In my scenario I am attempting to dispatch a new job during a console command, but it fails, because $pdo is null. Database related stuff only works, if called via DB facade, but job dispatcher needs a pdo connection object to work.
I wonder, if the pdo connection can be initialized manually, or is there any built in method/feature I can use, before dispatching my job?

So far this seems to be quite an obscure problem, widespread but no apparent native solution.

[TCM-RAN]

I have the same issue, it works 1 on 2 times, and I do not know how to fix it, tried so many things but still have the same issue.

Have you found how to fix it ?
