  • The error message "Cannot GET /" and the 404 Not Found response from http://localhost:4200/ indicate that the Angular development server is not serving your application as expected. This is not an ABP-specific issue, but a general Angular CLI/server problem.

  • This usually happens if you run ng serve (or yarn start/npm start) in the wrong directory, or if the Angular app was not built/installed correctly.

  Solution Steps:

  1. Navigate to the Angular Project Folder:

     • Make sure you are in the angular subfolder inside your ABP solution (e.g., MyApp/angular).

  2. Install Dependencies:

     • Run:

  yarn
  

   or
  

  npm install
  

  3. Start the Angular Development Server:
     • Run:

  yarn start
  

   or
  

  npm start
  

  • This should start the Angular app on http://localhost:4200/.

  4. Check for Errors:

     • If you still see "Cannot GET /", ensure you are not running another server (like Express) on the same port, and that your terminal output shows Angular CLI is serving the app.

  5. PWA Note:

     • If you used the -pwa flag, it should not affect local development, but make sure your environment is clean (no service workers from previous builds).

  Reference Screenshot: You should see the ABP Angular home page, not "Cannot GET /".
