Your PDB file has an atom named "H" in the first residue, but N-terminal
residues (in both the PDB-standard and Amber libraries) don't have such
an atom (they are called, instead, H1, H2, H3.)

Simplest thing is to remove the H atom from the pdb file and try again:
leap will build in the H1,H2,H3 atoms for you.

The error has nothing to do with copper.
