[NEST Users] stdp synapse nestml erro

I'm working with the nestml 7.0.2. I got the example models from https://github.com/nest/nestml/blob/v7.0.2/models/neurons/hill_tononi.nestml this git tree. I tried three different stdp models including stdp_triplet_naive.nestml. All give AssertionError: Synapses only support one spiking input port when I generate_target in python. -Chris
