NOT A BUG: _cat indices returning None for stats for some indices, raw curl returns data

[jascott1]

Elasticsearch version (bin/elasticsearch --version): 7.16.2

elasticsearch-py version (elasticsearch.__versionstr__): 7-7.17.9

Description of the problem including expected versus actual behavior:
Calling "cat.indices" returns None for some indices stats although curl _cat/indices returns actual stats.

Steps to reproduce:
Instantiate python Elasicsearch version 7 or 8 client.

Call "cant.indices(format=json,bytes=b)".

Observe problem index:
{'health': 'green', 'status': 'open', 'index': 'myindex', 'uuid': 'XyD5LntFQTO6Oc2VMpd2PA', 'pri': '1', 'rep': '1', 'docs.count': None, 'docs.deleted': None, 'store.size': None, 'pri.store.size': None}.

Compare to same index data from curl:

{
    "health" : "green",
    "status" : "open",
    "index" : "myindex",
    "uuid" : "XyD5LntFQTO6Oc2VMpd2PA",
    "pri" : "1",
    "rep" : "1",
    "docs.count" : "312963",
    "docs.deleted" : "0",
    "store.size" : "164202006",
    "pri.store.size" : "98032982"
  },

Notes:

• Same result with either client library major version (7 or 8)
• Elasticsearch has over 10k indices
• Data is consistently missing for same indices
• User is elastic with no changes to permissions

Thamks for any insights!

I am getting same result only using requests lib, so it is not a problem with elasticsearch.py. I will close this ticket but please comment if you have any suggestions as to what could be happening here!

This was self-inflicted permissions issues. What threw me off is that most indices were returning full stat data while only a subset were None. Thanks for the rubber duck session :)

Glad you sorted this out!
