NOTE:
This started to happen after RHEP patching and I had to start Ikasan dashboard manually and I suspect calling http://server:port/rest/metrics/1648141111466/1648141171466 subsequently trying to login to SOLR to http://server:8983/solr and then fails with authentication issue

Steps to reproduce

  1. Restart Ikasan dashboard
  2. Login to Ikasan dashboard as yourself
  3. http://server;port/swagger-ui.html#/metrics-controller/getMetricsUsingGET_2
    key in starttime as 0, endtime as 1651065981000
  4. You'll see you get a jibberish response
  5. WORKAROUND: If you harvest metrics data from a module and then try calling Metrics rest API returns empty data or correct data.
