When trying to use admin.firestore() part of firebase function execution, I am failing to create new documents, getting the following trace:
Error: Invalid use of type "undefined" as a Firestore argument.

I followed code samples in https://github.com/firebase/functions-samples and in the official Firestore documentation.
My code snippet:
const functions = require('firebase-functions')
const admin = require('firebase-admin')
admin.initializeApp();
exports.addNewUser = functions.auth
.user()
.onCreate(user => {
console.log(`user=${JSON.stringify(user)}`)
return admin.firestore().collection(`users`).doc(`${user.uid}`).set({
name: user.displayName,
email: user.email
})
.then(() => {
console.log("END")
return
})
.catch((error) => {
console.log(error)
});
})
Failing to perform set() operation here:
admin.firestore().collection(`users`).doc(`${user.uid}`).set({
name: user.displayName,
email: user.email
})
with message:
Invalid use of type "undefined" as a Firestore argument:
package.json file
"firebase-admin": "^5.12.0",
"firebase-functions": "^1.0.1",
db rules (no rules):
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write;
}
}
}
NOTE: making updates to ref object work well, only when trying to create new docs with full path, I get this behavior
