allow errors

Hang on, here! Are you
actually letting errors
occur on purpose? ARE
YOU MAD?!?

No. Not mad. And, yes. Letting errors occur.
If you try to code for every possible error, you’ll be at it for a
long time, because all that extra logic takes a while to work out.
Paradoxically, when you worry less about covering every
possible error condition, your coding task actually gets easier.
