Photodiode draws current from op-amp input
The op-amp you have chosen (LF412) is unsuitable for the power supply regime you show in your schematic. The input common-mode voltage range is a couple of volts inside the power rails hence putting the non-inverting input to ground (also your negative supply rail) is a mistake - you need bipolar supplies for this op-amp.
In addition, the minimum supply recommended for this op-amp is +/- 5 volts (a span of 10 volts) and you are showing it on a single 5 volt rail: -

This op-amp won't work properly on a single 5 volt rail.
