Absolutely, first of all, there are deprecation warnings in logs:

Yeah, unfortunately for end users that purely use OpenSearch Dashboards to build these scripts wouldn’t be able to see these messages unless they look at their logs as you stated which might not be likely. And do we know if these warning messages are enabled by default in a release (production) environment? And if it has gotten removed then when 3.0 comes then might wonder why their painless scripts no longer work.

I think we we can flag the original PR with “needs-documentation” it will create an issue in the documentation website repo to add these details. I think we need painless scripts logs in general and we can include the this was removed in 3.0 sections or will be removed in 3.0

With https://github.com/opensearch-project/OpenSearch-Dashboards/pull/1607, I have updated the stuff we utilized for sample data and tests so I have removed the bug label and re-added the enhancement to ensure end-users don’t get left with just an error message.

Right now, we don’t have a lot of control of the actual values within scripted fields and I wouldn’t recommend changing this value. However, based on the above mention PR’d this is an example of the kind of impact end-users will have to do if they utilized scripted fields (which is a huge feature in the application) and they are using deprecated methods that were removed.

Since this is a breaking change on the OpenSearch side, and the deprecation message has been obfuscated by OpenSearch Dashboards not outputting it to the screen. Users would have had to check their logs to see they should have been using a different method, which isn’t likely if everything is working properly.

I would prefer we give in application notification about the removal of deprecated methods in Painless Scripts and provide a link to some view that’s like if using x then use y or something like that which is why I tagged @opensearch-project/opensearch-ux to see if they could provide some help with this.
