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 } -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

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.
