Hi All,


 We installed and configured Grafana in our UAT cluster the UI which come up with default 3 dashboards cldb , node and volume. I see an exclamatory mark in red near Node Dashboard. I tried to fix it by adding a parameter in opentsdb.conf and then took a restart of opentsdb and grafana so was able to make CLDB Dashboard but the issue is with Node Dashbaord and when I click on the "!" mark I could see the below error any help would be much appreciated.
  "error": {
    "code": 400,
    "message": "Unable to parse the given JSON",
    "details": "com.fasterxml.jackson.databind.JsonMappingException: Filter cannot be null or empty (through reference chain: net.opentsdb.core.TSQuery[\"queries\"]->java.util.ArrayList[0]->net.opentsdb.core.TSSubQuery[\"tags\"])",
