Why am I getting an error in my ElasticSearch request after upgrading to 1.3.2?

I used to have this:

{
  query: {
    function_score: {
      filter: {
        and: [
          {
            term: {
              'currency': 'usd',
              '_cache': false
            }
          }
        ]
      },
      script_score: {
        "script": "_score * doc['random_score'].value"
      }
    }
  }
}

      

        
        
        
      

    

Very simple, I just filter the currency and sort by invoice.

But every time I update I can't get a simple custom counting query to work.

I tried to simplify it with this example:

{
  query: {
    function_score: {
      script_score: {
        "script": "_score * doc['random_score'].value"
      }
    }
  }
}

      

        
        
        
      

    

And I am getting errors like:

}

      

        
        
        
      

    

Something very simple like this works:

{
  query: {
    match_all: {}
  }
}
