Internal Server Error in Kibana

Internal Server Error in Kibana

Symptoms:

• In 5.1.1, an UnhandledPromiseRejectionWarning occurs and Kibana displays an Internal Server Error.

Resolution:

If the Security plugin is enabled in Elasticsearch but disabled in Kibana, you must still set elasticsearch.username and elasticsearch.password in kibana.yml. Otherwise, Kibana cannot connect to Elasticsearch.
