Just use address : req.body.address, and it should work fine.
Since your address is an array and you are sending address array as well in the request, you don't need to do anything else.
Try this:
const CreateStudent = new createStudent({
admisionnum: req.body.admisionnum,
first: req.body.first,
last: req.body.last,
phone: req.body.phone,
address : req.body.address ,
isActive: req.body.type
});
