我最近继承了一个 RT 安装，在将其升级到 4.2.12 后，无法再创建脚本。如果有人试图在特定队列或全局范围内创建脚本，就会发生这种情况。标准的“发生内部错误”消息被踢出。
当我查看系统日志时，我看到

有问题的代码位于 Scrip.pm 中的 Stage() 方法中
446 sub Stage {
447 my $self = shift;
448 my %args = ( TicketObj => undef, @_ );
449 my $queue = $args{'TicketObj'}->Queue;
450 my $rec = RT::ObjectScrip->new( $self->CurrentUser );
451 $rec->LoadByCols( Scrip => $self->id, ObjectId => $queue );
452 return $rec->Stage if $rec->id;
453
454 $rec->LoadByCols( Scrip => $self->id, ObjectId => 0 );
455 return $rec->Stage if $rec->id;
456
457 return undef;
458 }
我已经验证了 $args{'TicketObj'} 是未定义的。我有点不知所措，不知道接下来该怎么办。任何帮助我都感激不尽。

前任管理员做了一些指向错误网络路由的更改。我猜有些 URL 管道在发布之间发生了变化。
