Adding a Multi Lookup list item with pnp

I am having trouble adding a list item when including a multlookup field.

I have tried the following:

var dAssigned = ['168', '261'];
AssignedId: dAssigned


var dAssigned = [168, 261];
AssignedId: dAssigned

In both instances I get the following error:

If I remove the Assigned Lookup it works fine. I have verified this is the correct name on the remote list.

Dear @cwalter2,
Here, check this out - Working With: Items · SharePoint/PnP-JS-Core Wiki · GitHub

In short, it should be:

AssignedId: { 
    results: [168, 261]  // allows multiple lookup value

Yes that got it! Thanks
