which direction has the input current? Without bipolar supply voltage your circuit can only handle input currents which are flowing out of pin 2 of P2, from your circuit to the current source.
Take also care that due to the feedback loop of U2A pin 2 of U2A is on virtual ground. This can be problematic, if your circuit is driven by a voltage source. What exactly is driving the input of your circuit?
and which is the direction of current flow? Into the shown circuit (from the left to the right)? Or out of the shown circuit (from the right to the left)?
The shown circuit will only work with a current flowing out of the shown circuit (from the right to the left)!
Can you show a schematic of your constant current source?
