Using the local emulator, I'm trying to test a rule for my delete & update which looks like this:

match /posts/{postId} {
  allow read: if true;
  allow create: if true;
  allow delete, update: if (resource.data.user.uid == request.auth.uid)
}

In my test file, I write the path of the exact location of the existing doc that I'm trying to perform for example a delete on:

  it("If creator, Allow delete/update items in the post/comment collection", async () => {
    const db = firebase
      .initializeTestApp({ projectId: MY_PROJECT_ID, auth: myAuth })
      .firestore();
    const testDoc = db
      .collection("general")
      .doc("spaces")
      .collection("spaces")
      .doc("9LbUetZxWeL1ln5hv9ug")
      .collection("posts")
      .doc("RtUnezdAgXUfWmRSPpkF");
    await firebase.assertSucceeds(testDoc.delete());
  });

However when I run this test, it gives me this error. However, I know this doc exists and so does the user.uid I am looking to grab in my resource. Is there something wrong in how I'm trying to use this emulator?

I also saw that if I go into my local emulator firestore database, I can hard-code a file, specifically call route my test to it, then it works.
