First install only seeing a 404 page and `DEBU[0002] Strange: no context found for ''`

[deiga]

Description

I've just installed the plugin and wanted to try it out. But when I run helm dashboard I get a 404 page.

I've checked that kubectl config current-context has a correct context set and I've tried to start dashboard with helm --kube-context foo dashboard, but to no avail.

$ helm dashboard --verbose

helm dashboard --verbose

The debug message of Strange: no context for '' is a part of normal loading, so ignore it.

The normal session would produce logs from GIN about any attempt to access it. Like this:

undera@undera-primary:/tmp/downloads$ helm dashboard
INFO[0000] Helm Dashboard by Komodor, version 1.3.3 (b61adf133f639b8bffd43925b5b4b8230c197a26 @ 2023-06-22T08:59:05Z)

...

Even 404 would be reflected like this:

[GIN] 2024/03/06 - 18:40:27 | 404 |        7.05µs |       127.0.0.1 | GET      "/boo"

So it looks like your browser hits some other service or proxy instead of local dashboard. Please check that you don't have a proxy preventing you to access local sites.

I can also observe this kind of error when I execute as plugin directly inside the root folder of the project. I still don't know why though or if it is even a proof of something :disappointed: Executing helm dashboard on any other folder works to me

[undera]

@alessandrodetta What you see can be explained by this section in old code: https://github.com/komodorio/helm-dashboard/blob/v1.3.3/pkg/dashboard/api.go#L169 . However, it would produce explicit warning in log.

[alessandrodetta]

Oh now I see, that's why. I guess that's not the same problem then because there is no warning in his log as mine (i.e time="2024-03-08T15:31:30+01:00" level=warning msg="Using local development path to serve static files"). I actually have an empty static folder.

However, it seems that activating verbosity (--verbose) as he did doesn't produce the log to endpoints calls from GIN @undera Can you confirm this problem ? Or maybe they are written on a file somewhere else?

@deiga Can you try to execute just helm dashboard and see if in the log you get the call to endpoints (e.g GET "/" 404)? If still nothing gets reflected, maybe it is really something like a proxy/service intercepting the request.
