ThaMyind — Wed, 04 Jun 2025 02:58:10 GMT

Developing an application that pulls artist data. But I can even get to that point. Im trying to connect to authenticate with firebase and Im getting this error proccessing Spotify callback: 5 NOT_FOUND.

Ive been trying for days and cant get past this error.

has any one seen this?

My Oauth js

const functions = require('firebase-functions');

const admin = require('firebase-admin');

const { getSpotifyAuthUrl, exchangeCodeForToken } = require('./api_integrations/spotify');

// Initialize Firebase Admin SDK if not already initialized

if (admin.apps.length === 0) {

admin.initializeApp();

}

const db = admin.firestore();

/**

* Initiates the Spotify OAuth 2.0 authorization flow.

* Redirects the user to Spotify's authorization page.

exports.spotifyAuthRedirect = functions.https.onRequest(async (req, res) => {

try {

const { labelId } = req.query; // Expect labelId to associate the token

if (!labelId) {

functions.logger.error('spotifyAuthRedirect: Missing labelId query parameter.');

return res.status(400).send('Missing labelId query parameter.');

}

// Store labelId in session or pass it through state for callback

// For simplicity, we'll pass it in the state parameter (needs to be URL encoded)

const state = `labelId=${labelId}`;

const authorizationUrl = getSpotifyAuthUrl(state);

functions.logger.info(`spotifyAuthRedirect: Redirecting to Spotify for labelId: ${labelId}`);

return res.redirect(authorizationUrl);

} catch (error) {

functions.logger.error('spotifyAuthRedirect: Error generating Spotify auth URL', error);

return res.status(500).send('Failed to initiate Spotify authorization.');

}

});

}

let labelId;

if (state) {
