Exception in device view

Running headscale-ui 2022.08.13-beta, when navigating to the device view, I'm greeted with a broken page and this error in the console:

devices.html.svelte-b457f55c.js:1 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'length')
    at ul (devices.html.svelte-b457f55c.js:1:20977)

    at Object.p (devices.html.svelte-b457f55c.js:1:46456)

Other views (including user view) work fine. There are devices in my tailnet, so this is probably not a case of the list of devices being empty.

Thanks!

an empty headscale instance shouldn't cause a problem either. I can't recreate the problem. If you could answer the following questions I'd appreciate it

• Browser you're using (I only test chrome and firefox/firefox mobile)
• Version of headscale (please test with 0.16.2)
• Anything that might be unusual about your machines, special characters in names, that sort of thing

Does this happen with 2022.08.02.1-beta? If it doesn't, there might be something fishy happening with your headscale instance and the lastSeen field.

Ah, thanks for the pointer! I was running headscale 0.15, that was the issue. I upgraded and it fixed it.
