Shouldn't precommit body show up in cluster-info first before we try to
test it with an object? I just set the precommit hook for test_kv bucket
type which has no custom property set. Curl on props shows precommit, but
cluster-info doesn't (took another dump after 5 minutes of precommit hook
creation). No sasl logging is triggered either though the debug mode is on.
Curl output for test_kv props:

Cluster-info dump after setting the props - precommit body is still empty
in the cluster-info for test_kv bucket type:
