When using ThingISBN alone you get a warning :

Failed Can't use string ("1") as a HASH ref while "strict refs" in use at
/home/koha/src/C4/XISBN.pm line 99.

sub get_xisbns {
    my ( $isbn, $biblionumber ) = @_;
    my ($response,$thing_response,$syndetics_response,$errors);
...
    $response->{isbn} = [ @{ $syndetics_response->{isbn} or [] }, @{
$thing_response->{isbn} or [] } ];

Vars $thing_response,$syndetics_response must be initialised as an hashref.
Or maybe rewrite a bit this code.
