I'm basing it on the json from [Alert when okay](https://discuss.elastic.co/t/alert-when-okay/112707/4)

If you want to try it yourself, you can retrieve the default watcher through the GET api (GET \_xpack/watcher/watch/clusterid\_elasticsearch\_cluster\_status), make it into a watcher, fake the condition and simulate. Then you'll receive the runtime error

```
`"reason": "runtime error",
  "error": {
    "root_cause": [
      {
        "type": "script_exception",
        "reason": "runtime error",
        "script_stack": [
          "ctx.vars.is_new = ctx.vars.fails_check && !ctx.vars.not_resolved;",
          " ^---- HERE"
        ],`
```
