Job did not finish, requeued.

The code used:

        $this->loadModel('Queue.QueuedTasks');
        $this->QueuedTasks->createJob('Email', [
            'settings' => [
                'to' => ['testing@gmail.com'],
                'from' => ['testing2@gmail.com'],
                'subject' => 'testing',
                'template' => 'registration',
                'emailFormat' => 'html'
            ],
            'vars' => [
                'name' => 'tester'
            ]
        ]);

Can you please advice on the issue?

Thanks and great work on the plugin. Keep it up.

Sure, that arrays are allowed? Instead of

'to' => ['testing@gmail.com'],

did you try

'to' => 'testing@gmail.com',

?
Same for from (especially since that can only contain one email).

Hi Mark,

Thanks for getting back to me. The error are still the same even without array tag.

Can you please debug it and find out what email fails and why? I suspect you forgot one config or alike.
But this has nothing to do with the queue itself, it is basically invalid Email class setup.
