Need help configuing dap to debug C++ code

[AlphabetsAlphabets]

I have a few issues I have.

1. Keymaps are not being mapped, it doesn't matter how many times I press [b no breakpoint appears. When I run :nmap [b it shows that there are no maps for [b that exist. These are the maps for dap that I have defined.

-- Maps
Map("n", "[b", ":lua require'dap'.toggle_breakpoint()<CR>", {})
Map("n", "<F2>", ":lua require'dap'.continue()<CR>", {})
Map("n", "<F9>", ":lua require'dap'.step_over()<CR>", {})
Map("n", "<F10>", ":lua require'dap'.step_into()<CR>", {})

These maps are defined inside of debug.lua. I have required them in my init.vim.

lua require('tree')
lua require('debug')
lua require('tele')
lua require('line')
lua require('signs')
lua require('settings')
lua require('keymaps')
lua require('plugins')
lua require('packages')

Given that all of my other maps work I'm not sure why debug.lua isn't being sourced, it just doesn't make sense. This is what the debug.lua file looks like and it is made using instructions from here.

This is in a file called debug.lua.

local dap = require("dap")

-- Adapters need to be configured
dap.adapters.codelldb = {
  type = 'server',
  port = "${port}",
  executable = {
    command = '/home/yjh/Programs/codelldb/extension/adapter/codelldb',
    args = {"--port", "${port}"},

    -- On windows you may have to uncomment this:
    -- detached = false,
  }
}

-- Then a link is to be made to the adapter through neovim.
dap.configurations.cpp = {
  {
    name = "Launch file",
    type = "codelldb",
    request = "launch",
    program = function()
      return vim.fn.input('Path to executable: ', vim.fn.getcwd() .. '/', 'file')
    end,
    cwd = '${workspaceFolder}',
    stopOnEntry = false,
  },
}

-- Apply the cpp dap configs to rust
dap.configurations.rust = dap.configurations.cpp

-- Maps
Map("n", "[b", ":lua require'dap'.toggle_breakpoint()<CR>", {})
Map("n", "<F2>", ":lua require'dap'.continue()<CR>", {})
Map("n", "<F9>", ":lua require'dap'.step_over()<CR>", {})
Map("n", "<F10>", ":lua require'dap'.step_into()<CR>", {})

2. I get the error that there is no config for cpp detected.

No configuration found for `cpp`. You need to add configs to `dap.configurations.cpp` (See `:h dap-configuration`)

In my configs for I clearly do have cpp configured. I've seen some other configs for c++ I've managed to find and we have the same content aside from a few things so I'm not sure what's the issue here. There is one more thing I think I should add. I ran codelldb --port 13000. Problem is there is no output. I have no idea if I do actually get codelldb to start at port 13000. I have no clue if this is a problem wiht codelldb or not. Any help is appreciated, thanks :D
