arraySlice()/querySlice() with offset 0 throws StackOverflowError

Description

Using arraySlice() function, if the array is empty and the offset is 0 means it throws StackOverflowError. ACF throws an error like Cannot access array element at position 0. https://trycf.com/gist/459d8196c82d86b38113f5429917a0b3/acf2021?theme=monokai

Using empty query with offset 0 in querySlice() also throws StackOverflowError. ACF throws an error like The slice offset 0 is out of bounds. https://trycf.com/gist/84cc8541441ce5e4068827d82e74950f/lucee5?theme=monokai
It would be nice to throw an error like the array/query cannot be empty.

I've checked this ticket with the lucee latest build 6.0.0.144-SNAPSHOT and now arraySlice()/querySlice() with empty array/query throws error like cannot be empty instead of StackOverflowError.
