Definition of plugin "urlForwarding" not found and may have failed to load

Hi guys, after installing Elasticsearch on Kubernetes, I can access Elasticsearch, but when I tried to access Kibana, I encountered this error.

Version: 8.11.1
Build: 68203
Error: Definition of plugin "urlForwarding" not found and may have failed to load.

Looks like something happened during the install. Can you check the kibana logs right after starting it? It shows all of the plugins loading there and there might be a clue on what is wrong.

I encountered the same phenomenon. But in the kibana logs there were no logs about the problem

This issue does not generate logs. It seems that the cause is corrupted package information from artifacts.elastic.co

$ ./kibana-plugin install urlForwarding

Hello, I have also encountered this issue and have found a solution. Here are the steps I took: 1. Check if the transform node is missing and add it [ingest, transform]. 2. Try using the browser in incognito mode. If this issue is confirmed, it is suggested that the official documentation should note that missing a transform node can cause errors in Kibana, version 8.11.2.

I use reverse proxy

Also getting this with reverse proxy. I can access locally, but this pops up when i try using reverse proxy. I'm also having a couple separate issues I believe also though. Integrations can't connect, and I see issue with Unable to connect to Elasticsearch but then later elasticsearch service is now available. So maybe it is connecting fine there. Just integrations, http error.

Going to try downgrading to pre 8.x to 7.x. See if I have same issues. I'm just trying a fresh install using docker.

Have same issue with 8.x.x, raw linux install. Using caddy reverse proxy.
Noticed that it happens only while using Cloudflare DNS proxy.
