I have recently been making use of Laravel’s queues using the enqueue/laravel-queue package, with the enqueue/amqp-ext transport. This has proven to be very easy to work with and to implement.
However, in one of my queue jobs, I noticed that whenever I had a job that failed more than once, I’d receive the following error message:
Server channel error: -1, message: unexpected response
It turns out that this was because I was manually failing a job incorrectly - by calling $this->fail() followed by
$this->delete().
The solution to getting rid of this error is to either call $this->fail() or $this->delete() on the job - you
cannot call both and have it work correctly.
