Misleading category not found processing

[manasouza]

When some registry with unmapped category is processed alone, it fails and stop the processing.
In the same scenario but now while processing with other valid registries, it shows the warning only and records the registry as processed.

The fix should consider to not break the workflow, show the warning log and do not mark the registry as processed, so it could be evaluated again on the next run.

Wait until branch where pubsub fix was done to be merged to main branch
