我在打字稿文件中有这段代码

 function debug_show_removed_flights() {
    if ($('.debug-window #show_removed_flights')[0].checked) {
      $('.fly-schedule-removed_reason').show();
      return $('.fly-schedule-remove').show();
    } else {
      $('.fly-schedule-removed_reason').hide();
      return $('.fly-schedule-remove').hide();
    }
  };

但是在这一行中，我有错误。

if ($('.debug-window #show_removed_flights')[0].checked) {

[ts]属性'checked'在类型'HTMLElement'上不存在。

我该如何解决？

我已经下载了Honeybadger Webpack示例并运行bundle install。

我在终端中没有任何错误，但是在启动服务器时得到以下信息：

Webpacker can't find application.js in /Users/admin/Documents/sourcemap/honeybadger-rails-webpacker-example/public/packs/manifest.json. Possible causes:
1. You want to set webpacker.yml value of compile to true for your environment
   unless you are using the `webpack -w` or the webpack-dev-server.
2. Webpack has not yet re-run to reflect updates.
3. You have misconfigured Webpacker's config/webpacker.yml file.
4. Your Webpack configuration is not creating a manifest.
Your manifest contains:
{
}

适用于线 <%= javascript_pack_tag 'application' %>

我的问题在哪里？
