Thanks for the reply, indika. I think I made a small progress by removing the
'To' header in the fault sequence, but am encountering a different exception
now somewhere within axiom... Any clues why this may be happening? Thanks.

Subject: Re: Synapse endpoint timeout
Hi
Error you have got is related with malformed endpoint URL.You can see
the timeout handler has done timeout processing.
BTW, before sending error back to client, remove existing βtoβ header.
In your fault sequence, add β<header name="To" action="remove"/>β
before send mediator.
Thanks
Indika
