message

   @jiazhai yes happens each time. Steps:
   1. install pulsar 2.4.2 from the Helm Chart (I use Helm 3)
       - note: To get 2.4.2 working on Kubernetes, do the following workarounds:
         - turn off functions #5818
         - change the image spec for the Dashboard to 2.4.1 due to #5847 
         - check if admin api works on all proxy pods, and restart those which 
are stuck #5994
   2. create a tenant and a namespace
       - note: I create my namespace with:
          - `bin/pulsar-admin namespaces set-backlog-quota mytenant/mynamespace 
--limit 300M --policy consumer_backlog_eviction`
          - `bin/pulsar-admin namespaces set-deduplication mytenant/mynamespace 
--enable`
   3. publish some messages into a persistent topic in that namespace
       - note: I use Protobuf serliaization; I don't use message compression at 
this time
   4. go to the Dashboard, navigate to the topic, and try to view some messages 
currently residing on that topic
      - on the Dashboard webpage, when clicking on a message, nothing visible 
will happen (just a brief display of a loading indicator)
      - you have to open e.g. the Chrome web dev tools and look at Console or 
Network to see the 500 error returned
