I'm unable to query using the kafka storage plugin; queries are failing with a NPE which seems like a json typo:

Looking at the source, it seems like it's expecting the json field to be named

@JsonProperty("kafkaStoragePluginConfig")

(note the lower-cased 'k' at the start), but in the snippet in the error message it starts with a capital 'K'.
