Configuring nvim-dap for JavaScript and Python

Question

I'm looking to set up nvim-dap and followed the instructions for implementing it with Python and JavaScript, which seem very straightforward, but I can't seem to get it working. Here are my plugins:

-- Debugger
  use("mfussenegger/nvim-dap")
  use { "rcarriga/nvim-dap-ui", requires = {"mfussenegger/nvim-dap"} }
  use('theHamsta/nvim-dap-virtual-text')
  -- Python
  use ('mfussenegger/nvim-dap-python')
  require('dap-python').setup('~/.virtualenvs/debugpy/bin/python')
  -- JavaScript
  use { "mxsdev/nvim-dap-vscode-js", requires = {"mfussenegger/nvim-dap"} }
  use {
  "microsoft/vscode-js-debug",
  opt = true,
  run = "npm install --legacy-peer-deps && npx gulp vsDebugServerBundle && mv dist out"
}
    require("dap-vscode-js").setup({
    -- node_path = "node", -- Path of node executable. Defaults to $NODE_PATH, and then "node"
    -- debugger_path = "(runtimedir)/site/pack/packer/opt/vscode-js-debug", -- Path to vscode-js-debug installation.
    -- debugger_cmd = { "js-debug-adapter" }, -- Command to use to launch the debug server. Takes precedence over `node_path` and `debugger_path`.
    adapters = { 'pwa-node', 'pwa-chrome', 'pwa-msedge', 'node-terminal', 'pwa-extensionHost' }, -- which adapters to register in nvim-dap
    -- log_file_path = "(stdpath cache)/dap_vscode_js.log" -- Path for file logging
    -- log_file_level = false -- Logging level for output to file. Set to false to disable file logging.
    -- log_console_level = vim.log.levels.ERROR -- Logging level for output to console. Set to false to disable console output.
    })

    for _, language in ipairs({ "typescript", "javascript" }) do
    require("dap").configurations[language] = {
        {
  {
    type = "pwa-node",
    request = "launch",
    name = "Launch file",
    program = "${file}",
    cwd = "${workspaceFolder}",
  },
  {
    type = "pwa-node",
    request = "attach",
    name = "Attach",
    processId = require'dap.utils'.pick_process,
    cwd = "${workspaceFolder}",
  }
}
    }
end

As Instructed in the nvim-dap-python readme I also set up a dedicated virtual environment under ~/.virtualenvs.

When I go to a Python or JS file and run :lua require('dap').continue(), I get the response

No configuration found for 'python/javascript'. You need to add configs to 'dap.configurations.python/javascript

My understanding of the dap-python and dap-vscode-js plugins is that they configure it so you don't have to. I also tried adding an example configuration from :help dap-configuration, but it didn't seem to work.

When I source my packer.lua file I also get an error:

[packer.nvim] [ERROR 10:50:48] packer.lua:1022: Failure running setup function: "...ite/pack/packer
/start/nvim-dap-python/lua/dap-python.lua:96: nvim-dap is required to use dap-python"

I'm not sure what would cause this since nvim-dap is already installed.

Here's a link to my neovim-config repo: https://github.com/samcurteis/neovim-config/tree/main

Quick summary:

I tried setting up the plugins as per the instructions on nvim-dap, nvim-dap-ui, nvim-dap-python and dap-vscode-js. I also attempted to manually configure the dap.configuration without success. When I ran :lua require('dap').continue(), I expected the debugger to launch but it doesn't.
