I want to make a query that counts how many elements there are in the field that is a array of jsons objects.

When I run:

{script: { script: "doc['field\_name'].values.length() \> 0"}}

I get:

"No field found for [field\_name] in mapping with types "

I have set mapping for field\_name as nested, but still I am getting the same error

I have tried multiple variations for the query but none of them worked:

"script" : "params['\_source']['field\_name'].length() \> 1"  
"script" : "params['\_source']['field\_name'].size() \> 1"  
"script" : "params['\_source']['field\_name'].values.size() \> 1"  
"script" : "params['\_source']['field\_name.keyword'].values.size() \> 1"  
"script" : {"source": "doc['ctx.\_source.field\_name'].lenght() \> 0" }}  
and other variations.

What am I doing wrong ?

yes, a fully reproducible example, including index creation, mapping, document indexing and the query. Also, the Elasticsearch version you are using.

Thanks!
