I believe that I'm having trouble with field capitalization in my Nest queries on this topic. [ElasticSearch Nest query returning Null values for every field?](https://discuss.elastic.co/t/elasticsearch-nest-query-returning-null-values-for-every-field/284796)

I was told to try adding .DefaultFieldNameInferrer(p =\> p) to ConnectionSettings to fix this issue. However, when I have this added it gives me this error:

Elasticsearch.Net.Utf8Json.JsonParsingException : expected:'String Begin Token', actual:'1631555771000', at offset:344

I do not get this error when I do p.ToUpper() or p.ToLower(). What exactly am I doing wrong here?

For reference my objects look like this:
