[deal.II] Sparsity pattern error while applying periodic boundary conditions

Deal deal.II community, I want to apply periodic boundary conditions to my problem. But I can't use the make_periodicity_constraint() function due to the special nature of my problem (or so I think). So i create the required constraint matrix by taking the usual route of the AffineConstraints:
