It looks like you may have forgotten to set up HTTP Authentication in the Environment Variable. Currently, the file is called .env.example, while the script is looking for .env. For both your OpenAI API key and the secure login, you'll need to open a text editor (VS Code, Sublime, any other IDE), and either modify the name of the file or creative a new one called .env. From the ReadMe:

4. Set Up Environment Variables:

   • Create a .env file in the root directory.

     • Format shown in .env.example

   • Add your OpenAI API key and basic authentication:

      OPENAI_API_KEY=your_api_key_here
      USER_USERNAME=Username
      USER_PASSWORD=Password

If you're simply using Finder and want to use the default TextEdit, find the folder, use the shortcut CMD+Shift+. to show the hidden environment variable file. Then rename it to .env. The default is simply "Username" and "Password"; to customize it, double click/open the .env or .env.example and replace the values with whatever you'd like to sign in as. The Portal runs locally on your computer's port, so all the Basic HTTP Authentication is doing is securing the server for you. The more important part is adding your API key to the file so that it communicate with GPT-4.

I made a quick tutorial that you can follow the steps of if you're confused; it's just some extra setup so you can be sure no one's accessing your API key, as you choose the login credentials.
