Hi Godwin,
Call mediator blocking mode supportes indirect URL with key as you
mensioned above. Can you define the key expression in the endpoint.
<call blocking="true">
<endpoint key="gov:/testEndpoint"/>
</call>
@Isuru
Yes, call mediator with the combination of blocking=true and key-expression
in endpoint is not supported directly. We can use above approach.
Thanks,
Kathees
