Note the following from the Description:

In some cases, there may be multiple reasons for denying or detaining an entrant. For this exercise, you will only need to provide one reason.

It may be possible that the reason for denial given is just one of multiple reasons for denial. But it's also possible that you may have mixed up which documents pertain to which entrants during debugging. I'd suggest tweaking your debugging code to ensure the latter is not the case.

Probably it has been fixed or it was you mutating the input

for 1, raising an error is part of the criteria, but I agree with everything else

Can I safely skip this kata?

Yes. Pick any kata you want from the list, not the ones you get recommended.

i just now tried the same code and works fine for me
