Dear Paulina,
if it is a big expression, then please isolate
the minimal relevant piece that generates the error.
This should be easy enough e.g. as in
longExpression = Sum[a[i], {i, 1, 1000}];
longExpression[[1 ;; 500]] // fun;
longExpression[[1 ;; 250]] // fun;
longExpression[[20 ;; 250]] // fun;
until you get the smallest number of terms between
the lower and the upper bounds.
Once you are done with that, please provide me with
the output of
yourExp // FCE // InputForm
so that I can properly paste it into a Mathematica notebook.
I mean, if I can’t reproduce the issue on my computer,
then I can’t help understanding why it happens.
But for that I don’t need to see your full calculation, just
some small piece that generates the error.
Cheers,
Vladyslav
