Hello,

I have this error when I try to search for something using elasticsearch

```auto

```

I use:

- spring-data-elasticsearch version 4.4.0
- elasticsearch 7.17.6

I need to know if there’s a compatibility between the two librairies. And by any chance, is this error due to the fact that I am using version 7.17.6 and not 7.17.3 ?  
Because in the compatibility matrix I have this:
