How to configure the DAP debugger under neovim for typescript?

Question

I'm trying to configure the DAP debugger in Neovim for a typescript application.

I added the DAP plugin:

    use "mfussenegger/nvim-dap"

I also have a config.lua file containing the adapter and configuration:

      local status_ok, dap = pcall(require, "dap")
      if not status_ok then
        return
      end
      
      dap.adapters.chrome = {
        type = "executable",                                                                                                                                      
        command = "node",    
        args = {os.getenv("HOME") .. "/dev/dap-debugger/vscode-js-debug/out/src/debugServerMain.js", "45635"}
      }    
      dap.configurations.typescript = {    
        {    
        type = "chrome",    
        request = "attach",    
        program = "${file}",   
        debugServer = 45635,
        cwd = vim.fn.getcwd(),    
        sourceMaps = true,    
        protocol = "inspector",    
        port = 9222,    
        webRoot = "${workspaceFolder}"    
        }    
      }

When, under nvim in my typescript application project, I try to start the debugger with the :lua require'dap'.continue() command, I get the error:

Debug adapter didn't respond. Either the adapter is slow (then wait and ignore this) or there is a problem with your adapter or `chrome` configuration. Check 
the logs for errors (:help dap.set_log_level)

But the ~/.cache/nvim/dap.log DAP log shows no error:

    [ DEBUG ] 2022-04-12T08:49:37Z+0200 ] ...nvim/site/pack/packer/start/nvim-dap/lua/dap/session.lua:776 ] "Spawning debug adapter"    {
      args = { "/home/stephane/dev/dap-debugger/vscode-js-debug/out/src/debugServerMain.js", "45635" },
      command = "node",
      type = "executable"
    }
    [ DEBUG ] 2022-04-12T08:49:37Z+0200 ] ...nvim/site/pack/packer/start/nvim-dap/lua/dap/session.lua:965 ] "request"   {
      arguments = {
        adapterID = "nvim-dap",
        clientId = "neovim",
        clientname = "neovim",
        columnsStartAt1 = true,
        linesStartAt1 = true,
        locale = "en_US.UTF-8",
        pathFormat = "path",
        supportsRunInTerminalRequest = true,
        supportsVariableType = true
      },
      command = "initialize",
      seq = 0,
      type = "request"
    }

I can set breakpoints with the command:

    lua require'dap'.toggle_breakpoint()

I also installed the VSCode Js debugger with the following commands:

    git clone https://github.com/microsoft/vscode-js-debug
    cd vscode-js-debug/
    npm i
    gulp

I can see that my Chrome browser is listening on the 9222 port:

    chrome    208069        stephane  118u  IPv4 1193769      0t0  TCP 127.0.0.1:9222 (LISTEN)

If I run the debugger manually, I can see it starts on the given port number:

    09:16 $ node ~/dev/dap-debugger/vscode-js-debug/out/src/debugServerMain.js 45635
    Debug server listening at 45635

I'm on NVIM v0.7.0-dev

My Angular application is started and responds all right.

UPDATE: The debugger I was trying to use is not on DAP standard. I guess I need to find an alternative.
