Caused by: java.lang.ClassCastException: org.apache.spark.sql.catalyst.expressions.GenericRowWithSchema cannot be cast to scala.Tuple2

Details: Es version-6.3  
Incoming object example  
{  
"note":  
{  
"a":"1",  
"b':"2"  
}  
}

//Es properties used:  
.option("es.mapping.id", "note.a")  
.option("es.write.operation", "upsert")  
.option(ConfigurationOptions.ES\_UPDATE\_SCRIPT\_INLINE, "ctx.\_source.notefield.add(params.param1)")  
.option(ConfigurationOptions.ES\_UPDATE\_SCRIPT\_PARAMS, "param1:note")  
.option("es.write.operation", "upsert")

//the "notefield" is declared as nested in mapping at ES.  
Any suggestions
