-=== Known issues
-
-* In 8.1.0, a bug ({es-issue}84784[#84784]) can cause APIs that use filtered fields
-to return a `null_pointer_exception` error with a `401` HTTP status code when
-the `xpack.security.audit.logfile.events.emit_request_body` cluster setting is
-`true`.
-+
---
-When `xpack.security.audit.logfile.events.emit_request_body` is `true`, audit
-logs include the request body of incoming requests for certain events.
-These requests can contain sensitive information, such as passwords, that must not
-be logged. Fields containing such information are filtered out before logging.
-The REST APIs that use requests with filtered fields are:
-
-* <<security-api-change-password,Change passwords API>>
-* <<cluster-nodes-reload-secure-settings,Node reload settings API>>
-* <<security-api-put-user,Create or updates users API>>
-* <<security-api-get-token,Get token API>>
-* <<security-api-invalidate-token,Invalidate token API>>
-* <<security-api-grant-api-key,Grant API key API>>
-* <<watcher-api-put-watch,Create or update watch API>>
-* <<watcher-api-execute-watch,Execute watch API>>
-* <<security-api-saml-authenticate,SAML authenticate API>>
-* <<security-api-oidc-authenticate,OpenID Connect authenticate API>>
-* <<docs-reindex,Reindex API>>
-
-Please note the `xpack.security.audit.logfile.events.emit_request_body` cluster
-setting defaults to `false`. If the setting is `true`, audit logs only include
-the request body for the
-following events (not all of these events are enabled by default):
-
-* `authentication_success`
-* `authentication_failed`
-* `realm_authentication_failed`
-* `tampered_request`
-* `run_as_denied`
-* `anonymous_access_denied`
-
-To work around this issue, you can disable the request body auditing using the cluster settings API:
-[source,console]
-----
-PUT /_cluster/settings
-{
-  "transient": {
-    "xpack.security.audit.logfile.events.emit_request_body": false
-  }
-}
