We construct a wave-functional whose argument couples to boundary fermion currents in the AdS/CFT correspondence. Using this we calculate the contributions from bulk fermions to the chiral anomaly that give the subleading-order term in the exact N-dependence of the chiral anomaly of $\mathcal{N}=4$ SYM. The result agrees with the calculation of Bilal and Chu.
