[Firestore] Cannot get the doc data by path

[YaohanHu]

I use React Native to develop the app and integrate with firebase.

Now I encounter a problem. I want to use the path to get the doc data, but it can not works.

import '@react-native-firebase/app';
import firestore from '@react-native-firebase/firestore';

firestore()
 .doc('test/a/b/c')
 .get()
 .then((res) => {
   console.log('path exists', res.exists);  // false
   console.log('path data', res.data());   // undefined
 });

And when I get the doc step by step, then it will return the data.

import '@react-native-firebase/app';
import firestore from '@react-native-firebase/firestore';

firestore()
 .collection('test')
 .doc('a')
 .collection('b')
 .doc('c')
 .get()
 .then((res) => {
   console.log('step exists', res.exists); // true
   console.log('step data', res.data());  // Object {}
 });

Is there something wrong with the way I'm using it?

I found it's not an error. Just a typo.

I write the wrong path.
