[Koha] Error with Plack post upgrade to Koha 25.05.00.000

[Jonathan Druart]

Hello,

Let's focus on the error 500.
How do you get it?
My guess would be that you get "Array found where operator expected"
because there is a change between perl version (it seems to work ok for me
on 5.36, but with Ubuntu 22.04 you have 5.34).
May come from a perl's parser change and the different contextes involved
in the expression
  return @{$a} != @{$b} || notall { $_->[0] eq $_->[1] } zip6 @{$a}, @{$b};
Needs to be confirmed however.

Please clarify how you generate this error and I will try on Ubuntu 22.04.

Regards,
Jonathan
