Hi there! I see you're running into a 401 error with the message "Invalid API key" when trying to log in to the Player 2 app via Supabase. That error usually means that the API key provided to Supabase is either incorrect, expired, or not set properly in your app configuration.

To help you get this sorted out, can you tell me a bit more about the setup? For example:
- Are you using the anon (anonymous) or service_role API key in your app?
- Did you recently rotate or regenerate your API keys in the Supabase dashboard?
- Are you sure the API key is correctly copied and placed in the environment variable or config file your app reads from?
- Have you checked if the app is accidentally mixing up tokens, like using an API key where an auth token is expected?

While you answer, let me guide you through some key steps to troubleshoot:

1. Verify your API Key in Supabase Dashboard:
- Log in to your Supabase project dashboard.
- Navigate to Settings > API.
- Confirm you have the correct anon or service_role key. The anon key is usually for client-side usage (public), and the service_role key is server-side and more privileged; using the wrong one can cause errors.

2. Confirm API Key in App Configuration:
- Check your app’s environment variables or config files to make sure the exact key from step 1 is entered without extra spaces or encoding issues.
- If you use environment files (.env) with Windows, ensure the key is enclosed in quotes if it contains special characters.

3. Check your Authentication Calls:
- Make sure in your login/auth code you are passing the API key correctly to the Supabase client initialization.
- Your app should use the API key for Supabase client setup, but for certain requests (like supabase.auth.getUser()), you need to use an auth access token instead of the API key. Mixing these up can cause the 401 error 1.

4. If you recently changed the keys:
- Remove any cached API keys or old environment variables.
- Restart your app or development environment to ensure fresh loading of keys.
- Regenerate keys if you suspect compromise or corruption, then update your app accordingly.

If after these steps you still get the error, a good next step is to do a simple test:
- Create a minimal script or use Postman to try authenticating against Supabase with the API key you have. This isolates whether the issue is in your app or the key itself.

Go ahead and check these points, and let me know what you find. I’ll help you fine-tune from there! Are you ready to proceed?
