How to delete an item by uid dgraph-js

Did your mutation look like this?

	<_:new> <Post.postId> "1" .
	<_:new> <Post.username> "user1" .
	<_:new> <Post.likes> <0x1> .
	<_:new> <Post.comments>  <0x2> .
	<_:new> <Post.hashtag>  <0x32> .
	<_:new> <dgraph.type> "Post".

It needs to be “<_:new> <dgraph.type> “Post”.`” exactly as the name of the Type.
