Hey,
please format your messages properly. You can use markdown in this forum and you should to make your snippets way more readable.
Please take a look at the [painless documentation](https://www.elastic.co/guide/en/elasticsearch/painless/7.2/painless-walkthrough.html) as there is a short mention about the `replaceAll` method and why it takes function as the second argument.
