Hi, I am running the groovy script from JAVA which is something like this

> def value=DynamicValue  
> def Nvalue=NewValue  
> def field=Fieldvalue  
> def prod

> NewValue=NewValue.toInteger()  
> prod=doc[''+DynamicValue+''].value\*NewValue  
> if(doc[''+Fieldvalue+''].value != null)  
> {  
> doc[''+Fieldvalue+''].value=prod //here i am trying to update the field value  
> }

but when i am running the script i am getting an error like this

> {  
> "took" : 211,  
> "timed\_out" : false,  
> "\_shards" : {  
> "total" : 5,
