Boom! runtime error: invalid memory address or nil pointer dereference

[gerhard]

Describe the bug

Starting k9s fails with:

To Reproduce

Start k9s with an Active Context.

Versions

• macOS 12.7.2
• K9s 0.30.7 (0.30.5 & 0.30.6 have the same issue)
• K8s 1.28.4

Additional context

My workaround is to pin k9s to 0.30.4 which works as expected.

Attaching logs from:

• k9s-0.30.5.log - the first version that this issue appeared in
• k9s-0.30.7.log - the last released version which still has this issue

• Starting with context param gives runtime error #2388

@derailed if it helps, I'm happy to test a dev build.

I didn't go through the code diff, but this issue was introduced somewhere here: v0.30.4...v0.30.7

From the logs, it seems that there may be some issues with your configuration file located at /Users/gerhard/.config/k9s/clusters/changelog-production-2023-11-23/changelog-production-2023-11-23/config.yaml. Could you provide the contents of this file?

@gerhard Thank you for the heads up!

I think @wjiec is correct here.
Your context specific config must have an issue which we are not currently catching ;(
Best guess, your namespace section in this config is toast.
If you can share a mocked version that will help us zero in. Tx!!

I can confirm that this is now fixed in 0.30.8. I didn't change anything on my end, just updated & everything works now.

Found the problem!

Deleting this config, letting k9s generate its own, and then adding the custom skin property, fixed it. All good!

Thank you @derailed 💪

Unfortunately I still have the same issue, when running k9s v0.30.8 (latest at the time of writing) on MacOS v14.2.1.

Switching namespaces back and forth between bookmarked ones and default causes the issue, always. Running with default k9s config does not change the behaviour.

Same issue as above, changing namespaces in v0.30.8 results in a nil dereferenced pointer error on Windows.
