Hi Everyone:

Below nested update does not insert a new nested object in the array, Notice the added brackets []

curl -XPOST '[http://localhost:9200/v2/Test/cd196e01/\_update](http://localhost:9200/v2/Test/cd196e01/_update)' -d'{"script":"ctx.\_source.Code += Code",  
"params":{"Code":[{  
"Family":"Family",  
"Code":"Raw",  
"Code":12345,  
"Role":"",  
"Rank":4,  
"Description":"Some updates",  
"SourceType":"human",  
"SourceSequence":1,  
"SourceValue":"some value",  
"Status":"active"  
}]  
}  
}'

Getting error msg:

{"error":"ElasticsearchIllegalArgumentException[failed to execute script]; nested: GroovyScriptExecutionException[ClassCastException[java.util.HashMap cannot be cast to java.util.Map$Entry]

However, removing the brackets [] will update the existing nested object. Need to insert nested object instead.

Any help is much appreciated !!

Thank You
