An unexpected packet was received before the handshake. Dynamic EditTexts/Objectives two-way data binding

Question

Trying to make two way data binding on dynamic objectives in row_add_objectives.xml Got rid of all the red squigglies, but it keeps crashing :c What is the order of things that happens in handshake, and where would I start to look for the aforementioned unexpected packet?
