In DotNet using the Account.Create() results in an exception. | Appwrite | Page 1

When I try to create a new user with the following code
await _account.Create(userId: "unique()", email: email, password: password);

It hit an exception which says System.Collections.Generic.KeyNotFoundException: 'The given key 'expired' was not present in the dictionary.'

There is no dictionary on my side. It has to be Appwrite internal issue. Please help.
Edit: Account gets created but no User object is returned.
