Laravel Mail Queue

My code is raising the error Array to String conversion error. Currently I am implementing the mail queue for my application. Your task is to make it work. The attached class are called from the following line of code: $subject = 'Activation Email'; $name = $customer->name; $email = $customer->email; $token = $customer->token; $content = ''; $data = array( 'name' => $name, 'email' => $email, 'token' => $token, 'content' => $content ); $when = Carbon::now()->addSeconds(3); $emailJob = (new SendEmailJob($data))->delay($when); dispatch($emailJob);
