Exception when opening pages that loads preauthkeys from Headscale

Here's the exception:

I suspect that the reason is I have a pre-auth key without an expiration date:

ID | Key                                              | Reusable | Ephemeral | Used  | Expiration          | Created             | Tags

Are these pre-auth keys or headscale API keys? I think the error is with an API key that doesn't expire maybe?
Do you get an error on the Settings page when testing the key?

[maddie]

I think it's preauthkeys, I've only generated my first API key when installing the webui.

Key testing works fine, Routes and Machines page works too.

After manually UPDATE-ing the row with null expiration field in postgres, it works now.

It seems the newer Headscale doesn't allow creating pre-auth keys without expiration anymore, the database I'm using was created by a very ancient version of Headscale, so maybe that's why.
