Detect error on adapter in subscribe mode

Hi all,

I'm setting up a solution using the new ServiceNow adapter in subscribe mode, subscribing to events from a RabbitMQ topic. 

In this mode there's no response sent back to the bus, but since the adapter basically wraps a REST call, it could be that a 404 / or similar Http code is returned.

In this case nothing is logged by Neuron.

I've then set it up in solicit / response, the error is logged in the .adapter txt log when in info mode. That would not help in production.

I've then expanded the "OnReceive" process, invoking the adapter directly, and that gives me more control on the response, but also make the solution more complex to maintain and removes the possibility of using adapter policy to resubmit messages in case of network failure.

Can anyone suggest any other solution or point me in the right direction if I'm setting up something wrong?

Thanks

Fabrizio
