Looks like a duplicate of #13473? @ansjcy please reopen if I'm mistaken.

[jed326]

@andrross it's not a duplicate, this is for a newly introduced NPE that is breaking many builds. The other issue is an assertion error on a hit count.

[ansjcy]

@andrross this is different from #13473. The failures are from different code path. As I mentioned in the description, it's introduced this morning in https://github.com/opensearch-project/OpenSearch/pull/13888/files
