Question

Capture Smart Service Error Message from Expression

If a Smart Service has a onError argument, can I capture the error message of what went wrong?  For example, the createUser SmartService has an onSuccess and onError arguments.  In the onSuccess, I can capture the created user with fv!user.  Which is great.  But in the onError, I don't see anything that will tell me what went wrong.

I know the system knows what went wrong because if I happen to wrap the call to the createUser call in a WebAPI, I can see in the "Details" section of the "Smart Service Executed" response it says, "The username requested is not available".  But I want to capture that text so that I can log/report it and I don't see a way to do that.  I want to know more than "It failed".  I want to be able to report what actually went wrong.

Thanks in advance,
Steve

Did you see that this smart service requires that it is executed in the context of an admin account? Running it inside a user interface does not make much sense.

But, in general, I agree, the error cause should be available.

This was simply a trivial example to give some context to my question:  When running a smart service from an expression how does one capture what went wrong if/when it fails.

So, some smart service functions do return values if they fail. This would be documented. Like for a!startProcess
