Nope. Nothing to worry about. Carry on.
"No problem" is probably a better translatiom
That'd be 没有问题
Also often 没问题. 没事: it doesn't matter, not important, (so) "never mind"
This exercise also accepts "It's OK!"
Sometimes it means "never mind"
Why ‘It is nothing serious.’ is wrong?
That's a little too specific, but it can have that meaning. "Don't worry about it!"
I have been recently watching Chinese and Taiwanese dramas and I hear 沒事 like 15 times per episode! Useful phrase.
'That's nothing' should be accepted as well.
What would be a situation where this phrase is used?
Q)Bro you look pretty sad, are you OK? A)I'm fine/It's no big deal, I'm just a bit tired.
Google translate: "Fine!"
Why is 'nothing' not acceptable?
Is it also used in something like 没事，你呢?
"Doesn't matter" is not acceptable.
