Hi Guys,

I was playing with elastic search "Scripted Metric Aggregation", I get the error like this

```
{

```

"error": {  
"root\_cause": [  
{  
"type": "script\_exception",  
"reason": "compile error",  
"script\_stack": [  
"state.transactions = ",  
"^---- HERE"  
],  
"script": "state.transactions = ",  
"lang": "painless"  
}  
],  
"type": "search\_phase\_execution\_exception",  
"reason": "all shards failed",  
"phase": "query",  
"grouped": true,  
"failed\_shards": [  
{  
"shard": 0,  
"index": "transactions",  
"node": "O3HVsMQ3Tsamd\_rc9ECGUA",  
"reason": {  
"type": "script\_exception",  
"reason": "compile error",  
"script\_stack": [  
"state.transactions = ",  
"^---- HERE"  
],  
"script": "state.transactions = ",  
"lang": "painless",  
"caused\_by": {  
"type": "illegal\_argument\_exception",  
"reason": "Variable [state] is not defined."  
}  
}  
}  
]  
},  
"status": 500  
}

I was using the code in the ElasticSearch 6.4 document. Here is the link

[https://www.elastic.co/guide/en/elasticsearch/reference/6.4/search-aggregations-metrics-scripted-metric-aggregation.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.4/search-aggregations-metrics-scripted-metric-aggregation.html)

```
POST ledger/_search?size=0

```

{  
"query" : {  
"match\_all" : {}  
},  
"aggs": {  
"profit": {  
"scripted\_metric": {  
"init\_script" : "state.transactions = ",  
"map\_script" : "state.transactions.add(doc.type.value == 'sale' ? doc.amount.value : -1 \* doc.amount.value)",  
"combine\_script" : "double profit = 0; for (t in state.transactions) { profit += t } return profit",  
"reduce\_script" : "double profit = 0; for (a in states) { profit += a } return profit"  
}  
}  
}  
}

Can you please point out what is wrong? Do I have to declare them in the "params"?

What version of elasticsearch are you on? `state` was added in 6.4, that is why it is in the docs there, but not in 6.3 and earlier.

My fault. I though I was using 6.4, but I am using 6.3. Thanks
