How to filter on a high UNSIGNED8 value

I have an ID field in a file that is defined as an UNSIGNED8.
When I try to filter a high value ID like this:
OUTPUT(PeopleFile(id=18446714708963644565));
The compiler warns me: Warning: Condition is always false (8, 30), 1023, and my result is blank, although I can see the value stored in the file.

What am I missing? How can a filter on a large value? Lower values work OK, and if I cast the ID to a STRING value, it also filters correctly.

OUTPUT(PeopleFile((STRING)id='18446714708963644565')); //this works
OUTPUT(PeopleFile(id=187522928604396)); //this works too

Thanks!
