What would your preferred wording be?
'Detecting and managing an error' is about as succinctly as you could put it, isn't it?
Noticed and fixed a stuff-up, perhaps? Saw a f**k-up and took action?
I'm a bit of a pedant about grammar, spelling and punctuation myself, I'll admit, but it seems you're getting a bit het up (sic) about nothing in this case.
