Empty linkedId

[mike-aungsan]

I clone and run the code. Should not linkedId be number or do we have to config or code to insert linkId?

{
"_id" : ObjectId("562e99f598e23fee3f54ce0b"),
"name" : "Book 1",
"links" : [
{
"id" : 1,
"name" : "Author 1",
"notes" : "Note 1",
"linkedId" : NaN,
"linkedType" : "Author"
},
{
"id" : 2,
"name" : "Reader 1",
"notes" : "Note 2",
"linkedId" : NaN,
"linkedType" : "Reader"
}
]
}

Regards,
