Solr 8.6 / ZK 3.6.1 / Admin UI - ZK Status Null

    XMLWordPrintableJSON

    Details

    • Type: Bug
    • Status: Open
    • Priority: Minor
    • Resolution: Unresolved
    • Affects Version/s: 8.6
    • Fix Version/s: None

      Description

      When opening the Admin UI / ZK Status page it shows just null. Solr 8.6.0 / ZK 3.6.1. Zk is a 3 node ensemble.

      It seems to be cosmetic in the UI - otherwise Solr seems to work fine. Deleted already browser cache and restarted browser. Issue persists.

      In the logfiles I find the following error:
