I'm sorry, where does it say the German operator mistyped the key? The article says indeed that the message remained unsolved because it was sent on the wrong date, but I can't see the bit about the mistyping anywhere.

There is no typo in the key, just a typo in the encrypted message:
S4STEN
The S should probably be a 2 instead.
Is the ?4th a date?
