Cache Configuration for FlowPackJobQueueCommon_MessageCache has to be set

[paxuclus]

The Flowpack.JobQueue.Common package does not supply configuration for the backend of FlowPackJobQueueCommon_MessageCache: https://github.com/Flowpack/jobqueue-common/blob/master/Configuration/Caches.yaml#L1

Caches can be configured without a backend. They will fall back to SimpleFileBackend or FileBackend - not sure which ohne.

If the FlowPackJobQueueCommon_MessageCache does not have an explicit backend set, the fastrabbit process will fail:

Notice: Undefined index: backend in /Packages/Application/Netlogix.JobQueue.FastRabbit/Classes/Cache/CacheFactory.php on line 19

Notice: Undefined index: backendOptions in /Packages/Application/Netlogix.JobQueue.FastRabbit/Classes/Cache/CacheFactory.php on line 20

Fatal error: Uncaught TypeError: Argument 3 passed to Neos\Flow\Cache\CacheFactory::create() must be of the type string, null given, called in /Packages/Application/Netlogix.JobQueue.FastRabbit/Classes/Cache/CacheFactory.php on line 29

When setting a backend and backendOptions for the cache, the process runs as expected:

FlowPackJobQueueCommon_MessageCache:
  backend: Neos\Cache\Backend\RedisBackend
  backendOptions:
    hostname: '%env:REDIS_HOST%'
    database: 9
