Are you accessing code-server over HTTPS?

• I am using HTTPS.

• Color theme for VS code and code-server is the same in the screenshot.

I've also observed this issue from running code-server within a docker container based on ubuntu:22.04. code-server 4.4.0 worked fine without this issue, but it has been observed in 4.5.0.

I've installed code-server in a docker image defined here: https://github.com/pangeo-data/jupyter-earth/blob/master/hub.jupytearth.org-image/Dockerfile. It is based on ubuntu:22.04.

@RisaKirisu when you visit your code server, are you using a path like /code or such in the url, or is it straight up /? There is a fix (#5332) related to a failure affecting users that visits code-server via a path like /code.

I was curious if both you and me were users accessing code-server via a /prefix in the url like http://localhost/code or https://example.com/code compared to http://localhost or https://example.com/.

This should be fixed in 4.5.1

Yes. In my setup I access my code-server by 'https://mydomain.xxx/vsc/'. I don't know if this is the cause tho.

@RisaKirisu I think so. I believe the syntax highlighting happens thanks to a node module which isn't being loaded because it is assuming the root path. 4.5.1 should fix this

[jsjoeio]

For the curious, this issue should be fixed via #5332 when a new release comes out.
