[Hawkular-dev] Post a metricType under a resourceType, 400 bad request

Hi all, I was trying to create a metric type under my resource type called “MYRT”, Here’s body look like: {“collectionInterval”: 30, “id”: “metricTypeId123”, "type": "COUNTER", "unit": "NONE"} I posted this to url: http://localhost:8080/hawkular/inventory/deprecated/feeds/vertx-localhost... It gave me 400 bad request. But I posed to http://localhost:8080/hawkular/inventory/deprecated/feeds/vertx-localhost... . And it worked. Wondering why is that? Thanks
