TKT-6120
This send key was used for a message on another ticket
Why it happens
The idempotency key sent with this message was already used for a message on ticket #number. A key identifies one message on one ticket, so this message was not sent.
What to do
Send the message with a new key. To repeat the earlier message safely, use the same key on its own ticket.
