Check Incoming data is null

[AdityaReja]

I’m getting data out of LDAP and i nees to route it to two different mappers depending upon whether the incoming data is null or not. But i’m unable to do this… any solution?

There should always be some all important piece of data, like a key. You can reasonably assume the whole record is null if IT is. What are you trying to do?

@AdityaReja, some snaps perform no action if there is no input data (i.e. $ == null). You may need to augment your input to trigger the snap as has been explained in this post.

I also use the router snap and check if a field exists using the .hasOwnProperty() function

I got stuck using what they suggested, but there are a few options. Still the point is that some fields simply aren’t created.
