To resolve this issue, ensure that you’re providing valid credentials with your request. If you’re using an API key, check that it hasn’t expired.

final User user = securityContext.getUser();
if (user == null) {
return restChannel -> { throw new ElasticsearchSecurityException("there is no authenticated user"); };
}
final String username = user.principal();
final GetUserPrivilegesRequestBuilder requestBuilder = new GetUserPrivilegesRequestBuilder(client).username(username);
return channel -> requestBuilder.execute(new RestListener(channel));
}
