Question

In SystemJS Error#3, one type of cause is The javascript file was successfully downloaded, but failed during initial, top-level, execution, is there a way to catch that error in JavaScript? I am trying to get the error message and log it to the backend, right now it only shows up in user's browser console and no trace from the backend.

This is coming from system js importing a react build bundle file for single spa.
