Description: The lockToken function checks if a preimage hash is already in use with (is-eq (map-get? swaps {hash: preimageHash}) none). If an attacker can predict or know the hash an honest user intends to use (for example, by monitoring unconfirmed transactions), they can "front-run" the user by creating a swap with the same hash. This would block the honest user's swap due to the (err err-hash-already-exists) check.
