The 'Cut' operator. If I have a string that I want cut out some information I put in the start and end position. The problem comes in if I set an end position and the string is shorter than the total length I set then the I get an 'index out of range' error.
Instead of firing the error I should be able to say do not fault if the string is shorter than the stipulated range.

Hi @robin,
i've tried to reproduce it with the attached process and it does not fail? Can you share an example of a failing operator?

Hi @robin,
what operator are you talking about? Sounds like an easy fix.
