It seems like you code against a concrete implementation and not the interface Da\Mailer\Queue\Backend\MailJobInterface as the method getTimeToSend() does only exist in the following implementations of said interface: Da\Mailer\Queue\Backend\Beanstalk\BeanstalkdMailJob, Da\Mailer\Queue\Backend\Pdo\PdoMailJob, Da\Mailer\Queue\Backend\Redis\RedisMailJob.

var_dump(json_last_error_msg()); looks like debug code. Are you sure you do not want to remove it? This might expose sensitive data.
