Thank you, I'll try to keep that present (2 & null) after reviewing current code.
What is this RHS you are refering to please?

Uhm, not really on the possible error topic - as I experienced it differently.
....
Phew... i still had that in the terminal so I could scroll to it...

Code:
# | 45) swarm.util.mkdir                                                                     46) swarm.util.which | #

False positive grep?-swarm20-falsegrepjpg

This is with code of the 'initial' post/s ; where the 'catch' was different from the code we're talking about now (recent post with code).
This 'symbol' cannot be compared to a number, thus creating an 'expected' error message, which I wanted to get rid of -> as it breaks the visual experience.

Could you advice a better handling for this situation?
