tRestRequest --> tRestClient (how to manage responses)

[root]

Hello all, hope everyone is safe!

In my webservice (with tRestRequest), based on the inputs, I need to make a http call via tRestClient. The response (success/ failure) needs to be interpreted and my webservice needs to send a response back to the client... Something like:

tRestRequest --> Business logic --> tRestClient --> Response flow --> do something --> Send response (tRestResponse)
Error Flow --> do something --> Send response (tRestResponse)

As of this time, if the tRestClient returns a success, I see an error on the Karaf logs about some null pointer (reading the Error flow response code) and service responds back with a HTTP 500 Internal Server Error.

Whats the best way to handle this seamlessly? 

Thank you in advance.

How is the error flow connected to the main flow?
Verify you're not trying to send 2 responses.

Here is a snapshot of how this looks.If you see, the response is separate based the error/ success.

In the tRunIf conditions checks the errorCode (for Error Flow)/ statusCode (for Response Flow).

So, how can I make sure that ONLY correct flow is invoked based on the tRestClient... Hope that helps. Thanks
