Changing response from update from a script

I have an update script that updates the contents of a nested object array
and it works fine when everything is fine but sometimes we want to be able
to reject an update due to invalid parameters (such as a missing mandatory
field) and return an error.

I can set the ctx.op to none so that the _version isn't changed but that
only really works if the version is known before the request is made. So is
there something in ctx that can be changed so that an error response is
returned?

Code would be something like this:

if (myparam.mandatory == null)
{
ctx.op = "none"
// more here to return an error response
}

Hello Jennifer ,

I couldn't find any feature for this.
I feel this is a valid use case and i will file a bug on the same.

Thanks
Vineeth
