Hi All,

I am working on a watcher where I am getting the following error:

```
	at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) [?:1.8.0_222]
	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) [?:1.8.0_222]

	at org.elasticsearch.painless.antlr.PainlessParser.statement(PainlessParser.java:364) ~[?:?]

```

The code snippet I am trying to implement is as follows:

```
 "condition": {
    "script": {
      "source": "boolean trigger = false;def prov_list = new Map();for (var i = 0; i < ctx.payload.hits.hits.size(); i++){for (var r = 0; r < ctx.payload.hits.hits[i].recipient_count; r++){var userdata = ctx.payload.hits.hits[i].recipients[r].split('@');if(prov_list.has(userdata[0])){var counter = prov_list.get(userdata[1]);counter = counter++;prov_list.set(userdata[1], counter);break;}prov_list.set(userdata[1], 1);}}if (prov_list.size >= 2) {var iterator = prov_list.entries();for (var i = 0; i < prov_list.size; i++){if (iterator1.next().value.match('hotmail')){trigger = true;}}}return trigger;",
      "lang": "painless",
      "params": {
        "domain": "hotmail"
      }
    }
  }

```

Could someone please help me?

Thanks,  
Paul.

can you share the full stack response when running the execute watch API? There should be an indication in the stack trace where this refers to.

try replacing all your `var` with `def` statements. Also, `new Map` will not work (it's an interface in java), just do `foo = [:]` to create an empty map.

One last trick, running this using the execute watch API in the console, should show you exact error messages, which part of the script is having a problem, down to the exact character.

Thanks, how do I run it in the console, just copy & paste and run?

Use the [Execute Watch API](https://www.elastic.co/guide/en/elasticsearch/reference/7.3/watcher-api-execute-watch.html)
