This seems to be related to the performance analyzer of OpenSearch 2.13.0 and that is the base version of Wazuh indexer 4.9.x.

I saw a comment that disabling the performance analyzer (if this is unused) could solve the problem:

https://opensearch.org/docs/2.13/monitoring-your-cluster/pa/index/#disable-performance-analyzer

Wazuh indexer 4.10.x (unreleased at the time) will be based on OpenSearch 2.16.0 that should include the fix that solved the problem in OpenSearch 2.15.0 according to this comment: wazuh/wazuh-indexer#329 (comment)
