Can't require a file in the same directory?

[Nakilon]

I'm trying to start using LSP in Sublime Text 4.
My configuration:

    "ruby": {
      "enabled": true,
      "command": ["solargraph", "stdio"],
      "selector": "source.ruby | text.html.ruby",
      "initializationOptions": {
        // "diagnostics": true
      },
      "env": {"RBENV_VERSION": "2.6.6"}
    }

I have a file with module Common but it does not seem to see it:

Added this file:

$ cat .solargraph.yml 
include:
- "common.rb"

but it had no effect.
Am I doing it wrong?

Are you opening a single file without a workspace folder? If so, only the current file gets mapped.

If you're opening a workspace folder, you might need to make a .solargraph.yml configuration file with an include directive. More info: https://solargraph.org/guides/configuration

I'm looking into the possibility of being able to map files automatically when they're included in code with require_relative.
