AppwriteException: User (role: guests) missing scope (account)

client
    .setEndpoint(appwriteConfig.endpoint)
    .setProject(appwriteConfig.projectId)
    .setPlatform(appwriteConfig.platform);

const account = new Account(client);
const avatars = new Avatars(client);
const databases = new Databases(client);
const storage = new Storage(client);

export const getCurrentUser = async () => {
    try {
        const user = await account.get();

        const currentUser = await databases.listDocuments(
            appwriteConfig.databaseId,
            appwriteConfig.userCollectionId,
            [Query.equal('accountId', user.$id)]
        );

        if (!currentUser) throw Error;

        return currentUser.documents[0];
    } catch (error) {
        console.log(error);
        throw new Error('Error getting current user');
    }
};```

I am getting error while calling this function as soon as my app starts to get any logged inuser.
