using "now" in elasticsearch results in "could not read the current timestamp" error

using a "now" in my range query as shown below

 "range":{                    "metadata_fields.time_start":{                       "lte":"now",                       "gt":"now-7d"                    }                 }  

results in an error as shown below

{    "error" : {      "root_cause" : [        {          "type" : "parse_exception",          "reason" : "could not read the current timestamp"        }      ],      "type" : "search_phase_execution_exception",      "reason" : "all shards failed",      "phase" : "query",      "grouped" : true,      "failed_shards" : [        {          "shard" : 0,          "index" : "memsnippet_idx_1.1",          "node" : "XDHi_2BbSQGb33IHDasxfA",          "reason" : {            "type" : "parse_exception",            "reason" : "could not read the current timestamp",            "caused_by" : {              "type" : "illegal_argument_exception",              "reason" : "features that prevent cachability are disabled on this context"            }          }        }      ]    },    "status" : 400  }  

I upgraded to 7.11 today, my index.requests.cache.enable is true. Not sure why ES cannot read the current date?
