I cannot get Firebase AppCheck to work in production mode on a Vue.js project with Firestore and Storage. But It works normally in development.

const appCheck: AppCheck = initializeAppCheck(firebaseApp, {
  provider: new ReCaptchaV3Provider(reCaptchaSiteKey),
  isTokenAutoRefreshEnabled: true,
});

getToken(appCheck)
  .then((result: AppCheckTokenResult) => {
    console.log(process.env.NODE_ENV);
    console.log(result.token);
  })
  .catch((e: FirebaseError) => {
    console.log(process.env.NODE_ENV);
    console.log(e.code + ": " + e.message);
  });

In Development mode, using vite, get the token back: In Development mode

In Production mode, with firebase serve, get appCheck/fecth-status-error: enter image description here

Firebaser here!

The error you are receiving is due to the App Check backend not being able to verify the underlying reCAPTCHA attestation.

Things to check for:

  • is reCAPTCHA providing a valid attestation and not somehow thinking your device is a bot?
  • does the site secret uploaded to App Check for this App match the client ID you are using in the App?

If you are using a Debug Token in your development build, that might explain why that one is succeeding.
