We do this:

$err_obj->{_save_serializer} = $ser;
}
};
And then restore it:
hook after_error_render => sub {
my $response = shift;
my $err_obj = vars->{_save_err_obj};
if ( my $ser = delete $err_obj->{_save_serializer} ) {
set 'serializer', $ser;
}
};
After using this for a while, I noticed that after an error happens, the
serializer setting isn't getting restored. This simpler rewrite appears
to have the same effect, without the problem:
hook before_error_init => sub {
set('serializer', undef) if request->path !~ m{^/api/};
};
hook after_error_render => sub {
set('serializer', 'JSON') unless defined setting('serializer');
};
The restoration code is heavy-handed and violates the DRY principle, but
I think it will work for our purposes.
