Opensearch service fails to come up on perfsonar-toolkit installation

Start with /var/log/opensearch/opensearch.log and the failing /esmond/perfsonar/archive/ URL, then compare those errors with the pscheduler-archive authorization messages. The issue is resolved when OpenSearch initializes correctly and the archive endpoint no longer returns HTTP 500 or Unauthorized.

After installing perfsonar-toolkit on Rocky Linux 8.8, the following error is presented in the main screen (in a red box):

Error loading test listing; measurement archive unreachable:
https://myserver.example.com/esmond/perfsonar/archive/

If I try to access the URL above an error 500 is presented.

I'm repeatedly seeing the following errors on /var/log/opensearch/opensearch.log:

[2023-12-26T04:16:06,172][ERROR][o.o.s.a.BackendRegistry  ] [myserver.example.com] Not yet initialized (you may need to run securityadmin)

And the following message in pscheduler-archive logs:

archiver[17673]: archiver WARNING  < /head>< body>
archiver[17673]: archiver WARNING  <  h1>Unauthorized<  /h1>
archiver[17673]: archiver WARNING  < p >This server could not verify that you

archiver[17673]: archiver WARNING  credentials (e.g., bad password), or your
archiver[17673]: archiver WARNING  browser doesn't understand how to supply
archiver[17673]: archiver WARNING  the credentials required.</p>
archiver[17673]: archiver WARNING  </body></html>

What would be the reason for those errors? Is the archiver not able to use Opensearch? Is there any file where I should configure the auth tokens for the archiver to use Opensearch?

Thanks in advance.
