Firebase Storage "Permission denied" error

When I try to read my Firebase Storage data I'm getting the following error:

Uncaught (in promise) FirebaseError: Firebase Storage: An unknown error occurred, please check the error payload for server response. (storage/unknown)
{
  "error": {
    "code": 400,
    "message": "Permission denied. Please enable Firebase Storage for your bucket by visiting the Storage tab in the Firebase Console and ensure that you have sufficient permission to properly provision resources."
  }
} 

But my rules are set to public:

rules_version = '2';
service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write;
    }
  }
}

What am I missing? Here's my code:

export const getAll = async () => {
    let list: Photo[] = [];

    const imagesFolder = ref(storage, "images");
    const photoList = await listAll(imagesFolder);

    for(let i in photoList.items) {
        let photoUrl = await getDownloadURL(photoList.items[i]);

        list.push({
            name: photoList.items[i].name,
            url: photoUrl
        });
    }

    return list;
}
