I am try to implement firebase appCheck as mention in the official documentation https://firebase.google.com/docs/app-check/custom-resource-backend in the node back-end side.

version: "firebase-admin": "^9.3.0", node: v16.13.0

But i got a type error firebaseAdmin.appCheck is not a function with the example code given in the official documentation.

I tried with initializeApp with credentials, but no luck

CodePudding user response：

Firebase Admin "9.3.0" is very old version (released ~2 years ago, before App Check was GA). Try updating Firebase Admin to latest version:

npm i firebase-admin@latest
