Answer 1

Did you call admin.initializeApp()?

There are many official samples.

Answer 2

Everything worked for me the other day, so all setup was fine. But today I got this error.

Here's what solved it for me:

1. Revoked APNs Key
2. Created new one and downloaded it
3. Deleted old one and Uploaded it to Firebase Dashboard / Settings / Cloud Messaging
4. Gone to Settings / Service Accounts and generated new private key
5. Added it to my Cloud Functions project (renamed it to service-account.json in my case)
6. Saved the files and deployed the functions: firebase deploy --only functions

This error arises if your app setup for iOS has an error in any one of the following:

Found in Settings > General > Your Apps > iOS Apps:

• App Store ID
• Bundle ID
• Team ID

When adding an APNs key (Uploading to Cloud Messaging > APNs Authentication Key):

• Team ID (should auto set based off ios app info above)
• Key Id (often is in the name of the key, best to grab when creating it)
