When i use painless script, i get the following error:
Does this "plugin" mean the elasticsearch built-in aggregation function or something else?
Please don't post images of text as they are hard to read, may not display correctly for everyone, and are not searchable.
Instead, paste the text and format it with </> icon or pairs of triple backticks (```), and check the preview window to make sure it's properly formatted before posting it. This makes it more likely that your question will receive a useful answer.
Anyway the message means here that you need to write your own plugin (java code) in that case.
It would be great if you could update your post to solve this.
