Firestore write not working although security rules are set correctly

Question

I have set up the following security rule, because I only want Admins to be able to write to the collection enums:

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /enums/{test}/ {
      allow read;
      allow write: if request.auth.token.admin == true;
    }

When I am trying to write from the client I get the following error: Uncaught (in promise) FirebaseError: PERMISSION_DENIED: No matching allow statements although the request.auth.token.admin is set to true, as you can see in the following image:

I don't want to modify this: allow write: if true; because I am trying to develop some production ready rules.

Do you have an idea what I am doing wrong here?

Answer 1

I made the greatest mistake of all time here guys... a typo. My collection should be called enum instead of enums. It took me several days to find this out.

PS: Firebase is amazing :-)
