Review comment:
       I'm pretty sure the problem is with this line here. The return type is supposed to be ARRAY<BIGINT>, but the type returned here is ARRAY<ARRAY<BIGINT>>. I'm guessing it's because `x.getOperandType(0)` is an array type. Instead it should be the type of elements inside `x.getOperandType(0)`. (I'm not sure exactly what the method is to get that, but you should be able to figure it out using the debugger.)
