I upgraded Elasticsearch from 6.8 to 7.6 and after the upgrade values returned in the documents are all NULL.  
I do see the values coming in Debug information and total count is also correct but not sure why documents are NULL.

I tried suggestions mentioned in [ElasticSearch NEST - all fields are NULL](https://discuss.elastic.co/t/elasticsearch-nest-all-fields-are-null/221754) and [https://stackoverflow.com/questions/58175271/elasticsearch-net-nest-all-result-hit-fields-are-null-but-results-are-there](https://stackoverflow.com/questions/58175271/elasticsearch-net-nest-all-result-hit-fields-are-null-but-results-are-there) and still no luck.

I also tried adding property name and making them Pascal case and still no luck.

document is elasticsearch:

There looks to be a bug in handling properties with no setters; [I've opened an issue to address](https://github.com/elastic/elasticsearch-net/issues/4680).

In the meantime, if you add a setter for each property (don't need one for `FullName`) **and**

1. use `DefaultFieldNameInferrer(p => p)` _if_ the setter is public

or

1. use `PropertyNameAttribute` or `DataMemberAttribute` _if_ the setter is public _or_ non-public

then models will be hydrated.

Thank you @forloop. adding setter to the property resolved the issue. (If I see you in next ES conference I will buy you a drink 😆 )
