Unable to Load Cluster

[salomj]

Describe the bug

I am unable to load clusters into HeadLamp

To Reproduce

Steps to reproduce the bug:

1. Click either Load Cluster or Add Cluster
2. Upload KubeConfig
3. Leave the Box Check, and Click Next
4. Clusters successfully set up!
   No Clusters are loaded

Environment (please provide info about your environment):

• Installation type: Mac-Homebrew
• Headlamp Version: 0.29.0
• Other: Commit bbefb6e

Are you able to fix this issue?

No

Additional Context

• I tried reinstall via brew to no success.
• It worked fine for several weeks, with both local config and a non-prod config. I added a prod config, and then both the non-prod and prod config disappeared. And now I cannot add either.
• Not sure where to find the log file

Hi @salomj, can you please try it with the latest main. I am unable to reproduce this with the latest version.

Steps to test.

• Run backend cd backend && go run ./cmd -dev -enable-dynamic-clusters -proxy-urls=https://artifacthub.io/\*
• Run frontend cd frontend && npm i && npm start
• Run app cd app && npm run dev-only-app

I am encountering this issue as well with v0.30.0. Fresh, first time install this morning.

$ brew install --cask headlamp

Load Cluster > Load from Kubeconfig > Choose File > Finish

Results in cluster not loaded. Was working for ~30 minutes, but then clusters have disappeared from list after attempting to add more than 1 and now not able to add anything.

Can confirm the exact issue that @salomj is describing

• Installed via homebrew (v0.30.0 on macOS 15.4)
• Adding the first kubeconfig worked fine, then both disappeared after adding the second
• Now I cannot add any kubeconfig. It says 'successfully added', but nothing is showing

Thank you for confirming. Let me try it as well with the steps as mentioned

[knrt10]

Can you please try this if on Mac

• Open Headlamp app and open dev console cmd + option + i
• Go to Application Tab -> Storage -> IndexedDB -> kubeconfigs -> kubeconfigStore
• Clear the object store by clicking the stop button

Then try adding the cluster again and see if it works. Thanks

I had the same problem on my headlamp desktop version.

• version 0.30.0 installed with flatpak on Ubuntu 24.04 via the App Center.

@knrt10 suggestion fixed it (with ctrl + shift +i on my os)

Can you please try this if on Mac

* Open Headlamp app and open dev console `cmd + option + i`

* Go to `Application Tab -> Storage -> IndexedDB -> kubeconfigs -> kubeconfigStore`

* Clear the object store by clicking the stop button

Then try adding the cluster again and see if it works. Thanks
