Reproducing the problem

You can solve this with a one-liner( errStringified ) in plain javascript:

var error = new Error('simple error message');
var errStringified = (err => JSON.stringify(Object.getOwnPropertyNames(Object.getPrototypeOf(err)).reduce(function(accumulator, currentValue) { return accumulator[currentValue] = err[currentValue], accumulator}, {})))(error);
console.log(errStringified);

It works with DOMExceptions as well.
