ordered-by user for leaf-list throws commit exception

I added "ordered-by user" to preserve the order in which I created that leaf-list. However, now I am unable to write to the datastore for that augmentation and commit throws an exception.

augment "/inv:node
ext:augment-identifier resource-list;
leaf-list resource

Here is the exception I get:
