Looks like author. Validate is async so that your console. Log(document) statement at the bottom executes before the callback where you set document.
Author . You need to put the processing that depends on document. Author being set inside of the callback.
It looks like the answer is to use a callback to set the document. Author and to define author in the Schema.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
