open() fails

Hey. I have an error:

Can you provide your config for nvim-dap-ui?

[raphaelseher]

Had the same issue just now because I forget to call the setup method.

local dap, dapui = require("dap"), require("dapui")
dapui.setup()

I solved it, apparently the problem was my config with lazy.

  {
    "rcarriga/nvim-dap-ui",
    keys = {
      {
        "<leader>du",
        function()
          require("dapui").toggle()
        end,
        silent = true,
      },
    },
    opts = {
      icons = { expanded = "", collapsed = "", circular = "" },

        repl = "r",
        toggle = "t",

          size = 0.20,

how did you solve it exactly? Im using Lazy with the kickstart.nvim, I get the same error with an default dapui lua config file:

-- file: lua/custom/plugins/nvim-dap-ui.lua
return {
  'rcarriga/nvim-dap-ui',
  dependencies = {
    'mfussenegger/nvim-dap',
    'nvim-neotest/nvim-nio', -- Assuming this is also a dependency you want to include
  },
  opts = {},

  config = function()
    local dap, dapui = require 'dap', require 'dapui'
    dap.listeners.before.attach.dapui_config = function()
      dapui.open()
    end
    dap.listeners.before.launch.dapui_config = function()
      dapui.open()
    end
    dap.listeners.before.event_terminated.dapui_config = function()
      dapui.close()
    end
    dap.listeners.before.event_exited.dapui_config = function()
      dapui.close()
    end
  end,
}

This is my dap config:

return {
  'mfussenegger/nvim-dap',
  config = function()
    local dap = require 'dap'
    dap.adapters.gdb = {
      type = 'executable',
      command = 'gdb', -- Adjust this path as necessary
      args = { '-i', 'dap' },
    }
    dap.configurations.c = {
      {
        name = 'Launch',
        type = 'gdb',
        request = 'launch',
        program = function()
          return vim.fn.input('Path to executable: ', vim.fn.getcwd() .. '/', 'file')
        end,
        cwd = '${workspaceFolder}',
        stopAtBeginningOfMainSubprogram = false,
      },
    }

    dap.configurations.cpp = dap.configurations.c

    -- Load custom DAP key mappings
    require('custom.mappings.dap_mappings').setup()
  end,
}

The same error appears if I place a break point on my sample cpp code and run it

I have the same issue on Gentoo, what's the solution?

[bruteforks]

I had same problem. Although I was calling dapui.setup in my dap.lua, so I was puzzled. Anyway to test @raphaelseher's solution, I added require("dapui").setup() to my init.lua, and it works now. I guess the issue was the way I was calling setup from my dap.lua? Still unsure, but maybe it will help someone.

[gustavosinacio]

Check and see if you are missing the call to the setup function on the config function, as instructed in the usage section

[MZH-Amr]

Oh it was a stupid mistake on my end, I did dap.setup() instead of dapui.setup() 😳, I'm really sorry

[nurul5801]

Debug adapter reported a frame at line 74 column 1, but: Cursor position outside buffer. Ensure executable is up2date and if using a source mapping ensure it is correct

what is the prolem?
