How to reproduce the issue

Open any Rust project, hover over `main` and click on Debug.

Expected behaviour

The DAP UI debugger opens

Actual behaviour

The following error appears in messages:

.local/share/nvim/lazy/nvim-dap/lua/dap/session.lua:1186: EACCES: permission denied

I also set the DAP log level to DEBUG and I got the following log:

[ DEBUG ] 2024-02-07T19:41:03Z+0200 ] ...oris/.local/share/nvim/lazy/nvim-dap/lua/dap/session.lua:1165 ]	"Starting debug adapter server executable"	{
  args = { "--port", "64778" },
  command = ""
}

The minimal config used to reproduce this issue.

This is my rustaceanvim config using lazy:

return {
  'mrcjkb/rustaceanvim',
  version = '^4',
  ft = { 'rust' },
  opts = {
    server = {
      on_attach = on_attach,
      standalone = true,
      settings = {
        ['rust-analyzer'] = {
          cargo = {
            allFeatures = true,
            loadOutDirsFromCheck = true,
            runBuildScripts = true,
          },
          -- Add clippy lints for Rust.
          checkOnSave = {
            allFeatures = true,
            command = 'clippy',
            extraArgs = { '--', '-W', 'clippy::pedantic' },
          },
          procMacro = {
            enable = true,
            ignored = {
              ['async-trait'] = { 'async_trait' },
              ['napi-derive'] = { 'napi' },
              ['async-recursion'] = { 'async_recursion' },
            },
          },
        },
      },
    },
  },
  config = function(_, opts)
    vim.g.rustaceanvim = vim.tbl_deep_extend('force', {}, opts or {})
  end,
}

Hey 👋

I've converted this to a discussion, as the error is thrown by nvim-dap, and is unlikely to be caused by a bug in rustaceanvim.

Are you able to run codelldb --port 64778 from a terminal?
It looks like your OS or firewall could be blocking the port that nvim-dap is telling codelldb to listen on.

[mrcjkb]

Another thing you could try:
Does the same error occur when you debug using the :RustLsp debuggables command?

[BogdanFloris]

Yeah, the debuggables commands result in the same error.

I don't think it's related to the executable command not being correctly set. I tried setting it directly in the sessions.lua file in dap and it's still resulting in the same issue. Very weird stuff.

[ DEBUG ] 2024-02-07T21:12:06Z+0200 ] ...oris/.local/share/nvim/lazy/nvim-dap/lua/dap/session.lua:1166 ]	"Starting debug adapter server executable"	{
  args = { "--port", "65214" },
  command = "/Users/bogdanfloris/.local/share/nvim/mason/packages/codelldb/codelldb"
}

[mrcjkb]

Hmm, maybe your firewall is blocking the codelldb process spawned by neovim?
Or maybe your OS is blocking neovim from spawning the codelldb process?

Or perhaps the executable installed by mason doesn't have exec permissions?
When you run it from the terminal, are you running the binary installed my mason?

[BogdanFloris]

It wasn't that. Apparently in MacOS, you need to manually setup the codelldb handler in mason-nvim-dap.
