Im trying to switch from Firebase first gen to 2nd gen, and it already frustrated me,
this is just my code, simple

const {onDocumentCreated} = require("firebase-functions/v2/firestore");
   exports.totalGroup = onDocumentCreated(
   {region: "asia-southeast2"}, "tallyscan/{id}", async (event)=>{
      console.log("get event data");
      const snapshot = event.data();
      const id = event.params.id;
    console.log(snapshot);
    console.log(id);
  });

This the error

TypeError: Cannot read properties of undefined (reading ‘value’)
