Using a nested object property within custom_filters_score script

[Veda]

Hi,
  An example document in the index is
  {
    "title": "Red Gucci Dress",
    "merchant": "zara",
    "price": 1972.34,
    "colours": [{"name": "red", "emd": 1.98, "percentage": 45}, {"name":
"blue", "emd": 1.99, "percentage": 40}]
}

and i have defined a mapping to let ES know colours is a nested object by
posting the following json 

{
    "nested_product" : {
        "properties" : {
            "colours" : {
                "type" : "nested"
            }
        }
    }
}

I'm facing an issue when i want to use custom_filter_score and in the
scoring script I want to use the matched colour's properties to generate the
score. Below is the query 

{
  "query":{
    "custom_filters_score" : {
        "query": {"match_phrase": {"_all" : "gucci dress"}},
        "filters" : [{
            "filter" : { "nested" : { "path" : "colours",  "filter" :
{"term" : {"colours.name" : "blue"}}}},
            "script" : "foreach(colour : doc['colours'].values){ if
(colour.name == 'blue') {return ((0.1 * colour.percentage * colour.emd));}}"
            }
        ],
        "score_mode" : "total"
    }
}
}

which throws an error 

Query Failed [Failed to execute main query]]; nested:
CompileException[[Error: No field found for [colours] in mapping with types
[nested_product]]\n[Near : {... foreach(colour : doc['colours' ....}]\n         
   
^\n[Line: 1, Column: 1]]; nested: ElasticSearchIllegalArgumentException[No
field found for [colours] in mapping with types [nested_product]]; "

Any help on it would be appreciated

Thanks in Advance,
Veda
