Transform.GetAsync() not deserializing a percentiles aggregation with a script

NEST/Elasticsearch.Net version: 7.12.1

Elasticsearch version: 7.11.2

Description of the problem including expected versus actual behavior: I have a transform with an aggregation like this

            "my_median": {
                "percentiles": {
                    "script": "doc['field'].value * 2",
                    "percents": [
                        50
                    ]
                }
            }

But calling Transform.GetAsync() on that transform returns an object with the Script field as null

Steps to reproduce:

1. Create transform with a median aggregation based on a script
2. call Transform.GetAsync()
3. inspect returned object

Expected behavior The Script field should be non-null and match the transform definition

Thanks for confirming @karoberts. I’ll keep this open to track whether this can be safely implemented in 7.x.

@karoberts Apologies for the long delay on this one. I have added a serialisation fix which adds support for the string-based scripts that will go out in the next release.
