Error in $Ticket->AddLink(Type=>'MemberOf', Target =>$Father_Ticket )

Hi Ruslan,

The ticket exists in DB.
When I try the same command in other Queue, it works.
The both Queues have the same permissions for Everybody.
Do you know what could be wrong?

Always Cc the list.

No strong ideas except permissions. Add more debugging in
lib/RT/URI.pm around line mentioned in the log and in
RT::URI::fsck_com_rt file. Use $ticket->URI instead id, it may give
more clue.

Thanks.

Best regards, Ruslan.
