The Service Bus for the Connected Business

we have a service endpoint going out to a REST POST webapi.

if some of the property are not setup correctly in the request, the api will return a 422 error. However, we can't really see what the api is complaining about.

if i were to mimic the request and run it via PostMan, it will give me the "message" so i know what properties are missing/wrong.

so is there a way we can see the content of the error message in Neuron?

There are a number of ways to view the error information from a service endpoint.

  • You can catch the error in a try catch block and use a c# process step to see what the response from the service was.
  • You can look in the log files for the specific service endpoint (located in <install directory>\logs\<instance name> and review the information contained with in.
  • You can also add the REST code 422 to a list of excluded codes so that it does not throw an error and then check to see if that code is returned from the service using a C# process step. From there you can inspect the message returned from the service and then handle it however you see fit.

If you need additional help, or a demonstration of how to do any of these, please submit a support ticket on the neuron support site ( and I would be happy to schedule a webex session with you.
