I tried doing workarounds, but nothing seems to work - tried using "proxy" as verb, or portforward - all fails with similar error.
I collected logs from teleport-agent, seems to get nil dereference.

Probably related to #11712
from teleport.
@aviramha the fix is available #36079
Upgrading both Teleport proxies and Kube agents is necessary for this. Since you operate a Teleport cloud cluster, you'll need to wait through a merge, backport, and new release process before being able to test it.
I would appreciate it if you could provide me with the most concise steps to install metabear, allowing me to reproduce the issue. I've already tested it with #11712, and it functions correctly.
Ping me on slack if you prefer - tiago

Thank you @tigrato ! I'll ping you on Slack with instructions. Appreciate the prompt support <3

Update - @tigrato verified it works with our operator, thanks so much!
