Fails to detect ruby and confusing error "No workspace found" in sentry-ruby devcontainer

[solnic]

Description

Following up after https://bsky.app/profile/solnic.dev/post/3loix6q4xr62e

Reproduction steps

git clone https://github.com/getsentry/sentry-ruby.git
cd sentry-ruby
cp .devcontainer/.env.example .devcontainer/.env
code .

Then re-open in the devcontainer - our config is in .devcontainers dir. By default, the container is set up to grab bitnami/ruby docker image. Ruby is installed here:

$ which ruby   
/opt/bitnami/ruby/bin/ruby

This bin dir is in the PATH:

$ env | grep PATH | grep bitnami
PATH=/home/sentry/.bin:/vscode/vscode-server/bin/linux-arm64/17baf841131aa23349f217ca7c570c76ee87b957/bin/remote-cli:/home/sentry/.bin:/opt/bitnami/ruby/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/workspace/gems/3.4.2/bin:/home/sentry/.vscode-server/data/User/globalStorage/github.copilot-chat/debugCommand

Fails to run a test with confusing error

When trying to run a test, I get this:

Expected Result

Either of the two:

• IF it really cannot work with ruby under custom bin path, I would really expect to get a clear warning message that Ruby LSP did not manage to figure out where the ruby exec is, instead of "No workspace found" when running tests

OR, preferably:

• Fix it to actually detect properly where ruby exec is - it's in the PATH, there's no ruby version manager involved, it's the simplest use-case scenario, so it'd be great if it just worked OOTB

@vinistock you pinged me to report it so here it is - thanks for helping out!

@st0012 it's our sentry setup so maybe you could have some extra insights? 😄
