This looks identical to this posting

 

You can't modify the Master-Detail field when updating/upserting. In other words, you can't reparent if defined as Master-Detail.

Is there a way to work around this?

if you want to re-parent the master-detail relationship, you need to perform a delete and insert. its not a clean solution, but its a workaround.

What is the difference between Master/Detail Field type and Lookup Field Type?

I found I was receiving this error simply because I had not enabled reparenting on the master-detail relationship.
