### Problem Description

Sorting fails sometimes with the error

```
No TopN sorting encoder for type UNSUPPORTED
```


### Steps to Reproduce

Playing with ES|QL I tried to run the following query

`from logstash-* | sort extension.keyword`

This returns the error

```
No TopN sorting encoder for type UNSUPPORTED
```

If I run the query:

`from logstash-*  | keep extension.keyword | sort extension.keyword`

the data return successfully.
