I am facing issues deploying my Flutter web app to Firebase Hosting. The deployment process was working fine, but now I'm encountering a persistent HTTP 400 error with the message "Precondition check failed" during deployment. The deployment progress stops at 94%, indicating around 1050/1056 files.

-> firebase.json

{
  "hosting": {
    "public": "build/web",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ]
  }
}

.firebasearc

{
  "projects": {
    "default": "beta-realte",
    "beta": "beta-realte"
  },
  "targets": {},
  "etags": {}
}

web/index.html (firebase script)

<pre lang="HTML"><script type="module">
    // Import the functions you need from the SDKs you need
    import { initializeApp } from "https://www.gstatic.com/firebasejs/10.6.0/firebase-app.js";
    import { getAnalytics } from "https://www.gstatic.com/firebasejs/10.6.0/firebase-analytics.js";
    // TODO: Add SDKs for Firebase products that you want to use

    // Your web app's Firebase configuration
    // For Firebase JS SDK v7.20.0 and later, measurementId is optional
    const firebaseConfig = {
      apiKey: "AIzaSyDrSHgpYqh_PU_mcflJ55NZlgQ2kiEuHxI",
      authDomain: "beta-realte.firebaseapp.com",
      projectId: "beta-realte",
      storageBucket: "beta-realte.appspot.com",
      messagingSenderId: "761478122239",
      appId: "1:761478122239:web:9fa1e302a2edf0e30adaca",
      measurementId: "G-XF35Y47QGP"
    };

    // Initialize Firebase
    const app = initializeApp(firebaseConfig);
    const analytics = getAnalytics(app);
  </script>

What I have tried:

Troubleshooting Steps Taken:

Removed the 'redirects' section in the firebase.json file.
Upgraded Firebase tools.
Reran firebase init.
Deleted the .firebase folder and redeployed.
Attempted deployment on a new web app after deleting the current web app.
Tried different variations in the firebase.json file.

I've run the `firebase deploy --debug` command on terminal and this is the shortened version of the output I'm getting:
