Creating mock data fails because permissions

[johanneshayry]

Firestore emulator automatically applies the rules set in firebase.json. This could be mentioned in the code comments/tutorial. To write data you need to use initializeAdminApp, otherwise, the mock data write will probably fail because of the rules.

@johanneshayry Hey I encounter the same problem.
When trying to use a empty null auth object.
I got a error
Error: auth must be an object with a 'sub' or 'uid' field
Even when I created a object with sub and uid field it still failed.

Can you post the code you used with initalizeAdminApp to insert mock data.

Just a update I added the code to the helper function to insert the mock data with admin and return the test database using firestore rules

module.exports.setup = async (auth, data) => {
  const projectId = "rules-spec-${Date.now()}";
  const app = await firebase.initializeTestApp({
    projectId,
    auth
  });

  const db = app.firestore();
  const dbAdmin = firebase.initializeAdminApp({projectId}).firestore();

    if (data) {
      for (const key in data) {
        const ref = dbAdmin.doc(key);
        await ref.set(data[key]);
      }
    }
  
  // Apply rules
  await firebase.loadFirestoreRules({
    projectId,
    rules: fs.readFileSync('firestore.rules', 'utf8')
  });

  return db;
};

@avacadoadam Remove "rules": "firestore.rules", in firebase.json.
