Missing HN data in the firebase API

FYI - I'm scanning the HN Firebase API and I got a list of documents that failed today. It seems the documents exist on HN but not in the HN Firebase API. Most of the ids are above 16158000

Here are some ids: 16159148,16159106,16158408,16158404, 16158403,16158397,16158392,16158389, 16158385,16158383,16158382,16158381, 16158380,16158377,16158375,16158373

There's about 100 from today.

Has this happened before? Are there mechanisms to ensure the firebase data is accurate?
