Input bias current is an unavoidable feature of op amps that arises because the input impedance of op amps is actually not infinite and there is some current that must flow into the inputs when the op amps are operating.

This video describes why input bias arises, the effects that it has on the circuit, and ways to mitigate the effects of input bias currents.
