Hi Manzoor ,
You can try the $.keys().length expression in the mapper snap. This will give you length of array that will contain all headers from the source.

Unfortunately, no. When you preview the parent, you can only see the preview output of the snaps in the parent. There’s no way to see the preview output of the snaps that executed in the child during the preview of the parent. The preview output that you’re seeing in the child pipeline is left from when you last previewed just the child pipeline by itself.
Taylor,
Thank you. I am bit more clearer and closer to the fix now. I enabled all the snaps and all but validated one. Please see attached. I tried with and without toggling the “=” button but neither works.
Those expression buttons are toggled off. You definitely need them on. What’s the error when they are on?
