How can I resolve the 'Unable to detect a Project Id' error on Vercel despite setting environment variables?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I have an Astro website that collects stamps and a React API that reads from a Firebase database. Everything works fine locally, but when I deploy to Vercel, I encounter this error:

Error fetching stamps: Error: Unable to detect a Project Id in the current environment.

I’ve already updated the environment variables on Vercel as shown below, but the error persists:

FIREBASE_PRIVATE_KEY_ID=YOUR_PRIVATE_KEY_ID
FIREBASE_PRIVATE_KEY=YOUR_PRIVATE_KEY
FIREBASE_PROJECT_ID=YOUR_PROJECT_ID
FIREBASE_CLIENT_EMAIL=YOUR_CLIENT_EMAIL
FIREBASE_CLIENT_ID=YOUR_CLIENT_ID
FIREBASE_AUTH_URI=YOUR_AUTH_URI
FIREBASE_TOKEN_URI=YOUR_TOKEN_URI
FIREBASE_AUTH_CERT_URL=YOUR_AUTH_CERT_URL
FIREBASE_CLIENT_CERT_URL=YOUR_CLIENT_CERT_URL
API_KEY=YOUR_API_KEY
AUTH_DOMAIN=YOUR_AUTH_DOMAIN
PROJECT_ID=YOUR_PROJECT_ID
STORAGE_BUCKET=YOUR_STORAGE_BUCKET
MESSAGING_SENDER_ID=YOUR_MESSAGING_SENDER_ID
APP_ID=YOUR_APP_ID
MEASUREMENT_ID=YOUR_MEASUREMENT_ID

Has anyone encountered this issue or have suggestions for how to pass the credentials correctly so that Firestore can detect the Project ID in the Vercel environment? Thanks for any help!

It looks like your Firebase service (in this case, Firestore) can’t find a project ID because the credentials aren’t being passed correctly in the Vercel environment. When you run locally, you’re probably loading your service account (and its project_id) properly, but on Vercel the automatic detection fails. Here are some points to check and fix:

  1. Explicitly Provide Your Credentials:
    Rather than relying on automatic detection, pass the service account’s credentials (including the project_id) when initializing Firestore. For example, if you’re using the Firebase Admin SDK, you can do something like this:

    JS
    import admin from 'firebase-admin';

// Make sure to replace escaped newline characters if needed
const privateKey = process.env.FIREBASE_PRIVATE_KEY.replace(/\\n/g, '\n');

if (!admin.apps.length) {
  admin.initializeApp({
    credential: admin.credential.cert({
      projectId: process.env.FIREBASE_PROJECT_ID,
      clientEmail: process.env.FIREBASE_CLIENT_EMAIL,
      privateKey: privateKey,
    }),
    // Optionally, you can also specify other config options like databaseURL
  });
}

const firestore = admin.firestore();

  2. Verify Your Environment Variables on Vercel:
    Double-check that you’ve set the environment variables (such as FIREBASE_PROJECT_ID, FIREBASE_CLIENT_EMAIL, and FIREBASE_PRIVATE_KEY) correctly in the Vercel dashboard. Remember that the service account’s private key often contains newline characters. On Vercel you may need to store them with escaped newline characters (i.e. using “\n” instead of an actual line break) and then replace them in your code as shown above.

  3. Use the Correct Variable Names:
    Sometimes there can be confusion between the regular Firebase config variables (used on the client) and the service account credentials (used on the server). For administrative access (to Firestore for example), you’ll need to use a service account’s credentials. Confirm that you are using the correct ones and that the key names match (for instance, using FIREBASE_PROJECT_ID for your project ID).

  4. Check Vercel’s Build Settings:
    Make sure your environment variables are available to the serverless functions—sometimes configuration in Vercel might restrict which variables are available at runtime.

By explicitly passing your credentials (with the project ID) when initializing Firestore and ensuring that your environment variables are configured correctly (including handling newlines in your private key), you should be able to resolve the “Unable to detect a Project Id” error.

For more details, you can refer to the Google Cloud authentication guide:
