Solution

  • There is a space in your raw transaction between 55c0371 6901000. Remove it. Also, it should be as simple as that:

    signrawtransaction 010000000164518c0612559b8b47af331be4b33741ebed40298ce1df557e99e8955c0371690100000000ffffffff01809698000000000017a9147ecbc7d9cbb793ffb9a2905876c49f19cef8f75a8700000000

    You should not need the other arguments as it uses whatever is available. This question is a good reference.
