Never really got this "One error can bring down all "monolith services"".

Can you share one example where an error couldn't be handled gracefully in a monolith?

Say if my shipping service fails for some reason, I can still fallback to a default cost in a monolith.

Agreed. I've found propogating an error across multiple services to be a much harder problem than handling it with return values/exceptions in a monolith.
