Errors in browser console (if relevant):

GET http://localhost:5601/vzl/api/console/api_server 400 (Bad Request)
failed to load API 'undefined': {"statusCode":400,"error":"Bad Request","message":"uri [http://0.0.0.0:5603/api/console/api_server] with method [get] exists but is not available with the current configuration"}

Provide logs and/or server output (if relevant):

Any additional context: The request to /api/console/api_server is sent using jQuery ajax. This needs to be refactored to use the Kibana http client instead. See this file for more details
