Attaching to debug port via PM2 process (TypeScript/Node.js)

[FiNEk]

Hello! I am having trouble debugging a Node.js process launched via PM2. Essentially, I am launching a Node.js process and exposing a debugging port using the --inspect={some_port} flag.

I’ve managed to boil it down to the most minimal example repo possible:
https://github.com/FiNEk/ts-pm2-nvimdap-problem

I can attach to that process with ease, but I can’t set breakpoints or pause the process. When I try to set a breakpoint, I just see an exclamation mark on that line and breakpoint just doesn't stop execution.

When I try to pause the process, I see a dialog pop-up asking ‘Which thread?’ with no threads available. However, I know for sure that I am attached to the right process and DAP is working because I can see logs in the REPL.

I am using LazyVim, so the nvim-dap configuration looks like this:
https://github.com/LazyVim/LazyVim/blob/main/lua/lazyvim/plugins/extras/dap/core.lua
https://www.lazyvim.org/extras/dap/core

With following additions to setup node debugging.

  {
    "mfussenegger/nvim-dap",
    optional = true,
    dependencies = {
      {
        "williamboman/mason.nvim",
        opts = function(_, opts)
          opts.ensure_installed = opts.ensure_installed or {}
          table.insert(opts.ensure_installed, "js-debug-adapter")
        end,
      },
    },
    keys = {
      {
        "<leader>dd",
        function()
          require("dap").disconnect()
        end,
        desc = "Detach",
      },
    },
    opts = function()
      local dap = require("dap")
      if not dap.adapters["pwa-node"] then
        require("dap").adapters["pwa-node"] = {
          type = "server",
          host = "localhost",
          port = "${port}",
          executable = {
            command = "node",
            -- 💀 Make sure to update this path to point to your installation
            args = {
              require("mason-registry").get_package("js-debug-adapter"):get_install_path()
                .. "/js-debug/src/dapDebugServer.js",
              "${port}",
            },
          },
        }
      end
      if not dap.adapters["node"] then
        dap.adapters["node"] = function(cb, config)
          if config.type == "node" then
            config.type = "pwa-node"
          end
          local nativeAdapter = dap.adapters["pwa-node"]
          if type(nativeAdapter) == "function" then
            nativeAdapter(cb, config)
          else
            cb(nativeAdapter)
          end
        end
      end

      for _, language in ipairs({ "typescript", "javascript", "typescriptreact", "javascriptreact" }) do
        if not dap.configurations[language] then
          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
      end
    end,
  },

I have no idea how to even approach this problem, so any help is appreciated.
