Briefly, this error occurs when a request is made to Elasticsearch without proper authentication. It means that anonymous access is not allowed for the requested action. To resolve this issue, you can either provide valid credentials with your request or configure Elasticsearch to allow anonymous access. However, allowing anonymous access can pose a security risk, so it’s generally recommended to use authenticated access. Another solution could be to check and correct the permissions of the user making the request if they are not set correctly.

localNodeInfo.prefix; originAttributes(threadContext; message; localNodeInfo); action;
arrayToCommaDelimitedString(indices.get()); message.getClass().getSimpleName(); opaqueId());
} else {
logger.info("{}[transport] [anonymous_access_denied]\t{}; action=[{}]; request=[{}]{}"; localNodeInfo.prefix;
originAttributes(threadContext; message; localNodeInfo); action; message.getClass().getSimpleName();
opaqueId());
}
