If you haven't yet done so, do a Google search on Amber "does not have a
type". You'll get the general idea.

Your pdb file has a N-terminal alanine with an H atom in it. But the
Amber library for alanine in an Nterminal position uses H1/H2/H3, but no

Simplest solution is to remove the H atom from the pdb file: tleap will
build in the H1/H2/H3 for you.
