`Uncaught TypeError: JSON.parse(...).error is undefined`

Nothing has changed, just load the page which has worked for a long time and I get a undefined error due to the object not containing `error` property. If you provide a private contact I can forward the object details causing the error. Just looking at the data in the console, it doesn't seem like an error object but rather a data object.
