# Jordan-Wigner map for ionic molecule H_2^+

I want to derive the Hamiltonian of the ion molecule $$H_2^+$$ by making use of Jordan-Wigner map. Thus, I used qiskit nature. I wrote down the same command given in qiskit nature. The only difference is that I changed the charge number from 0 to 1. Then it generates following error message

If you know any method to fix it, please teach me. Thank you for your time.
