Problem with jcr:created property in initial content loading

[Daniel, de la Cuesta Navarrete]

 Hi,

I am loading custom initial-content in the repository using a json file

This is  my json:

{
  "jcr:primaryType" : "nt:unstructured",
  "sling:resourceType" : "mycompany/content",
  "jcr:created" : "",
  "jcr:createdBy" : "",
  "jcr:lastModified" : "",
  "jcr:lastModifiedBy" : ""
}

It is strange because all properties are created except the jcr:created,

I always get a 404 (Resource not found) error when I try to acces this
property

Any idea?
