Firebase AppCheck POST request is unknown

I'm trying to configure AppCheck in my web app (using SvelteKit).

I've registered my web app with recaptcha and then Added this basic code:

        onMount(async () => {

            const appCheck =  initializeAppCheck(app, {
        provider: new ReCaptchaV3Provider('my-key'),
        isTokenAutoRefreshEnabled: true
            
    })
})

But it fails with 400 error. Those occur because the POST request has 'unknown' where the Recaptcha (and firebase collection) should be.

POST URL: https://content-firebaseappcheck.googleapis.com/v1/projects/undefined/apps/undefined:exchangeRecaptchaV3Token?key=undefined

Why does it happen? how can I fix it?

*The only similar case is here, but it has no solution, and might not be the same.

Solution

  • SOLVED: The request was malformed due to mistaken firebaseConfig data.
