Internal Server Error on /routes #69

Closed ngreenwood6 closed 1 year ago

ngreenwood6 commented 1 year ago

It looks like the feature to view the routes was just added which is awesome. However, when I try to view the page it just gives an "Internal Server Error". The docker logs show the following:

Can you give me the output of the routes ls command on your Headscale servers? headscale routes ls

iFargle commented 1 year ago

All my routes are ordered but I'm not sure it's the correct way to do it.. So I just take the route ID and subtract 1 for the index in the array. It's likely you have deleted routes or something so the index is "wrong"

ngreenwood6 commented 1 year ago

Yeah I definitely have been messing around and removed routes. Here is the output:

After looking at this I also noticed that by removing machines that I setup those routes on it didn't remove the routes. Shouldn't it be removing those routes when the machine is removed? I am not sure if this is a "UI" issue or an "API" issue. Maybe I should put this on the head scale repo?

iFargle commented 1 year ago

Its a pre-v0.21.0 Headscale issue. The latest version fixes it for everything except ephemeral nodes timing out

I need to rewrite my code to get this working properly. Sorry about that. I'll work on it when I have time :).

Actually that may have been an easier fix than I thought. Can you pull ghcr.io/ifargle/headscale-webui:testing and give it a shot? if this works I'll move it into main :)

18 | | 192.168.99.0/24 | true | false | false Let me do one more fix. This will still display empty routes but at least it won't error out :)

iFargle commented 1 year ago

(For now, you'll need to manually delete the routes through Headscale's CLI, my UI doesn't have a way of deleting routes, just enabling/disabling)

Try pulling a new build on testing. It should display now

ngreenwood6 commented 1 year ago

Just wanted to let you know on the latest the page is working. Thanks for the quick response.
