The error
PHP Fatal error: Uncaught Predis\Response\ServerException: CROSSSLOT Keys in request don't hash to the same slot in predis/predis/src/Client.php:370
We are encountering this with the predis client.
The cause and possible solution
We believe the issue is specifically that migrateExpiredMessages isn't compatible with redis cluster mode. It looks up queue-name:reserved instead of {queue-name}:reserved. We were able to do a hacky workaround by naming all of our queues in {} thus forcing a specific node in the cluster.
https://github.com/php-enqueue/redis/blob/master/RedisConsumerHelperTrait.php#L102
It seems like the configuration options of the enqueue wrapper could more easily support the predis cluster config options.
