Hi, 

The link field expects a variant key.  It seems like you are passing the 
entire document.  Use the getVariantKey() method to get the variant key.  

So in your flowscript you'll have something like this : 

var document = repository.createDocument(...);
var linkTargetDocument = repository.createDocument(...);
// do stuff
linkTargetDocument.save();
document.setField("linkField", linkTargetDocument.getVariantKey());
document.save();

hth,

Paul
