### Problem Description

We are trying to migrate from Elasticsearch 6.7.1 to Elasticsearch 8.6.0.

With the same document we always get IndexOutOfBoundsException while trying to fetch innerhits in Elasticsearch 8.6.0. Everything works fine in Elasticsearch 6.7.1.


### Steps to Reproduce

[elasticsearch_6.7.1 (1).txt](https://github.com/elastic/elasticsearch/files/10466823/elasticsearch_6.7.1.1.txt)
[elasticsearch_8.6.0.txt](https://github.com/elastic/elasticsearch/files/10466824/elasticsearch_8.6.0.txt)
