The current documentation at [https://www.elastic.co/guide/en/x-pack/current/condition-script.html](https://www.elastic.co/guide/en/x-pack/current/condition-script.html) indicates in several places and examples that X-Pack Watcher script conditions can use other languages than "painless".

I just tried with Python and got back the error "Watcher: [illegal\_argument\_exception] script\_lang not supported [python]".

Is the current documentation wrong?

Looks like the above link was for X-Pack 6.2. I think the word "current" here and in the url threw me off:  
 ![2%5D%20_%20Elastic](https://us1.discourse-cdn.com/elastic/original/3X/f/3/f3d42b347eff0a56237f286568063a9af8bdf344.jpg)

This seems to be the updated doc page for 6.3:  
[https://www.elastic.co/guide/en/elastic-stack-overview/current/condition-script.html](https://www.elastic.co/guide/en/elastic-stack-overview/current/condition-script.html)

It still mentions other languages, and uses "lang": "javascript" in the example:

Other languages can be used, but `python` was removed as a scripting language. You could still use a custom script engine (java plugin).
