Description

I am not able to get gri or grt to work. But others like grn or grr work without any problems. I don't know where to start to check what i could do otherwise, because some do work and some don't. It works in other languages like JS.

Note:
I am on 0.12.0 and added the plugin with vim.pack.add({{ src = "https://github.com/mrcjkb/rustaceanvim" }}). Maybe something does not get loaded correctly?

Debugging, testing, running everything works. I am just not able to jump to definition.

Example Code

-

Neovim version (nvim -v)

v0.12.0 (nightly)

Operating system/version

Endeavour OS

Hey 👋

If you are having issues with rustaceanvim, please follow the troubleshooting guide in the readme.
If you can reproduce the issue with a minimal config (using the latest non-nightly Neovim release), please open a bug report.

Otherwise, there's nothing I can do to help.
