Es6.promise.js file: Unable to get property raise of undefined or null reference

Question

I have a react app that triggers this exception right when I attempt to setState. I find the exception in a file called es6.promise.js. Does anyone know what package this file is from and what this error is about?

I don't know if this has anything to do with it but I'm using wijmo's collectionView to set my state to it.

this.setState({rowData: collectionView});
