I noticed this as well with the recommended docker-compose.yml from https://opensearch.org/docs/latest/install-and-configure/install-opensearch/docker/. When I replaced the latest tag with 2.15.0 the Discover page works as expected. So it seems this is a bug introduced in 2.16.0.

Also seeing this using 2.16.0. Reverted to 2.15.0 and it worked.

We're running into this on a fresh deploy of 2.16.0 as well. I tried to roll back Dashboards to 2.15.0, but am getting the following error trying to start up Dashboards:

 FATAL  Error: Setup lifecycle of "securityDashboards" plugin wasn't completed in 30sec. Consider disabling the plugin and re-start.

If anyone has any suggestions, I'm all ears. Right now, I'm thinking it's some issue with the Security index, and I'll need to do a full redeploy down to 2.15.0 on the Opensearch nodes as well.

Edit: Okay, the issue was Dashboards crashing was actually our OIDC configuration. Proxy support for OIDC was added in 2.16.0, and that's something we use. After disabling OIDC, I was able to back up to 2.15.0, create some Index Patterns, then upgrade back to 2.16.0, and Discover is working!

Can it be fixed in the next version?

Can it be fixed in the next version?

I have a PR to fix this #8082, that will need @kavilla to help review
