Record Field send/handle Not Found
Do you see a type error related to this? This might mean that you've passed self to a helper function of your render, and it used it like so: <div onClick={_e => self.send(Click)} />. This is because the record can't be found in the scope of the file. Just annotate it: <div onClick={_e => self.ReasonReact.send(Click)} />.
