Describe the bug

neotest-golang runs a single test, but cannot start debugger for the same test.

Note: neotest-go starts the debugger (though it runs for all tests in the module 😢 ), but neotest-golang fails with an error:

neotest-golang: ...vchenko/.local/share/nvim/lazy/nvim-nio/lua/nio/init.lua:119: The coroutine failed with this message:

Steps To Reproduce

1. Start a debugger for a test case
2. An error occurs

Expected Behavior

Should run the debugger

Your Lua setup

Using LazyVim I configure:

return {
  "nvim-neotest/neotest",
  opts = {
    adapters = {
      -- "neotest-go",
      "neotest-golang",
    },
  },
  dependencies = {
    {
      -- {
      --   "nvim-neotest/neotest-go",
      --   extra_args = { "-vet=off" }
      -- },
      {
        "fredrikaverpil/neotest-golang",
        args = { "-vet=off" }
      },
    },
  },
}

Please provide a minimal reproducible Go test example.

Check out https://github.com/golang-jwt/jwt , run go build ./... to make sure it builds, then run neovim in the dir and execute a debug test.

I cloned down the repo, found a test at random and tried to both run it and then debug it. Works on my machine 😄

It feels like this could be a configuration issue on your end...?

Since LazyVim is already using neotest-golang, I could quite easily try it out here too, and it works for me:

Could it be that you haven't enabled debugging in your neotest-golang config with dap_go_enabled = true?

What happens if you run :checkhealth neotest-golang?
