Debug adapter definition and debug configuration

local dap = require("dap")

dap.adapters["pwa-node"] = {
  type = "server",
  host = "127.0.0.1",
  port = 9229,
  executable = {
    command = "js-debug-adapter",
  }
}

for _, language in ipairs { "typescript", "javascript" } do
  dap.configurations[language] = {
    {
      type = "pwa-node",
      request = "launch",
      name = "Launch file",
      program = "${file}",

Actual Result

Error: Couldn't connect to 127.0.0.1:9229: ECONNREFUSED

Sounds like either js-debug-adapter isn't listening on 9229 or it takes too long to start up, in which case you could increase the retries via the max_retries option.

In any case, I don't see how this is a bug and this isn't a support forum to troubleshoot configuration problems.
