I keep getting this error of a script exception, but I'm not sure what the root cause is.
[script\_exception] compile error, with { script\_stack={ 0="... tx.payload.aggregations.4XXerror.buckets.size(); i ..." & 1=" ^---- HERE" } & script="if (ctx.payload.hits.total \< 1) return false; for (int i=0; i \< ctx.payload.aggregations.4XXerror.buckets.size(); i++) { if (ctx.payload.aggregations.4XXerror.buckets[i].doc\_count \> 10) { return true; }}" & lang="painless" & position={ offset=90 & start=65 & end=115 } }
Any suggestions?
```auto
"condition": {
"script": {
"source": "if (ctx.payload.hits.total < 1) return false; for (int i=0; i < ctx.payload.aggregations.4XXerror.buckets.size(); i++) { if (ctx.payload.aggregations.4XXerror.buckets[i].doc_count > 10) { return true; }}",
"lang": "painless"
}
}
```

I suppose you need to check for the existence of the `buckets` array, as it might be empty - this is just a guess however.
First, please always format your exceptions as well, makes it much more readbale.
Second, if you add `min_doc_count: 10` to your aggregation, the bucket will only be returned if it contains more than ten documents. With this change in your query in place, you just need to check if the size of the `buckets` is greater than 0.
If it still does not work, please share the **full** output of the execute watch API.
Thanks!

Thanks for the help.
Turns out the issue was naming.
You cannot use numbers to name the fields you're calling as it causes an error later on.
In my case: `4XXerror`.
I renamed it to `errors`, and it works perfectly fine.
