Uncaught (in promise) Error: [Vuetify] Could not find injected layout
firebase_auth.js?v=d855205c:6920 Cross-Origin-Opener-Policy policy would block the window.closed call.

1. **Vuetify Layout Injection Error**:

Uncaught (in promise) Error: [Vuetify] Could not find injected layout

This means Vuetify is looking for a layout component (like `v-container`, `v-main`, or `v-app`), but it’s not finding one. Try wrapping your “ component inside a `v-app` tag if it's not already inside one in your main layout.

**Solution:**
Ensure that `v-app` is included at the top level of your app, typically in `App.vue`:

<template>
     <v-app>
       <router-view />
     </v-app>
   </template>

2. **Cross-Origin-Opener-Policy (COOP) Error**:

firebase_auth.js?v=d855205c:6920 Cross-Origin-Opener-Policy policy would block the window.closed call.

This error is related to Firebase authentication's popup handling in Chrome. It occurs when COOP is set in a way that blocks the `window.close()` function that Firebase calls when closing the authentication popup.

**Possible Fixes:**
– If you're using **Strict COOP (`Cross-Origin-Opener-Policy: same-origin`)**, try removing or adjusting it to `same-origin-allow-popups` in your server’s response headers.
– If you're using Firebase's popup authentication, try switching to **redirect-based authentication**:

import { signInWithRedirect } from "firebase/auth";
     
     const signInWithGoogleRedirect = () => {
       const provider = new GoogleAuthProvider();
       signInWithRedirect(auth, provider);
     };

– Ensure that your app is served from `https://` and not `http://`, as this can also cause issues.

Would you like to check your `server.js`, `.htaccess`, or `nginx.conf` configuration for COOP headers?

### 🔴 **Issues with Serving Over HTTP**
1. **Firebase Authentication Restrictions**
– Many authentication providers (Google, GitHub, etc.) **require HTTPS** for OAuth redirects and popup authentication.
– The **popup-based login** (e.g., `signInWithPopup`) may not work properly due to browser security restrictions.

2. **COOP (Cross-Origin-Opener-Policy) Issues**
– Browsers enforce stricter security policies for **cross-origin requests**, causing errors like:

Cross-Origin-Opener-Policy policy would block the window.closed call.

– Some features of Firebase, like popup authentication, **do not work properly in HTTP environments**.

3. **Service Worker Restrictions**
– If you're using Firebase Cloud Messaging (FCM) or Progressive Web Apps (PWA), **service workers require HTTPS** to function properly.

### ✅ **Workarounds for Development on HTTP**
If you're developing locally over HTTP (`http://localhost`), here’s what you can do:

#### 1️⃣ **Use `localhost` Instead of IP Addresses**
– Firebase allows HTTP **only on `localhost`**, not other local IPs like `192.168.x.x` or `127.0.0.1`.
– Make sure you are accessing your app via:

http://localhost:3000

– If you're using a custom domain, consider adding an entry in `/etc/hosts` (Linux/macOS) or `C:WindowsSystem32driversetchosts` (Windows):

127.0.0.1 myapp.local

Then access it via `http://myapp.local`.

#### 2️⃣ **Switch to Redirect Authentication Instead of Popup**
If `signInWithPopup()` isn’t working, use **redirect-based authentication** instead:

import { signInWithRedirect } from "firebase/auth";
   import { GoogleAuthProvider, getAuth } from "firebase/auth";

   const auth = getAuth();
   const provider = new GoogleAuthProvider();

   const signInWithGoogleRedirect = () => {
     signInWithRedirect(auth, provider);
   };

**Why?**
– The redirect method is more stable for **non-HTTPS environments**.
– Works better with browsers that block popups from insecure origins.

#### 3️⃣ **Adjust COOP Headers on Localhost**
If you have control over the server headers, allow popups with **Cross-Origin-Opener-Policy**:
– For **Apache**, add this to `.htaccess`:

Header set Cross-Origin-Opener-Policy same-origin-allow-popups

– For **Nginx**, modify `nginx.conf`:

add_header Cross-Origin-Opener-Policy same-origin-allow-popups;

### 🔒 **Best Solution: Use HTTPS with a Self-Signed Certificate**
For local development, it's best to **serve your app over HTTPS**. You can create a **self-signed SSL certificate**:

#### ➤ **For Laravel with DDEV (Your Setup)**
Since you're using DDEV, simply run:

ddev config --host-http-port=8080 --host-https-port=8443

Then access your site via:

https://yourproject.ddev.site

DDEV automatically generates a valid certificate for localhost.

#### ➤ **For Docker Setup**
If using Docker, add a self-signed certificate and run your server on HTTPS:

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout localhost.key -out localhost.crt

Then configure Nginx or Apache to use `localhost.crt` and `localhost.key`.

—

### 🎯 **Conclusion**
– **If using `localhost`, Firebase Authentication should work fine** over HTTP.
– **For remote testing (e.g., `192.168.x.x`), switch to HTTPS**.
– **If popups fail, switch to redirect-based login**.
– **Consider DDEV or a local HTTPS setup** to avoid future issues.
