DOM event objects provided as errors are hard to troubleshoot

[dtinth]

Some code (not sure if ours or 3rd party) seems to be throwing an Event object.

This is a commonly-misused pattern in JavaScript world.

something.onerror = e => {
  throw e
}

It would help if the event name and event target class name is serialized in Datadog RUM.

Hi @dtinth, browsers intentionally hide errors thrown by script files from different origins for security reasons.

You could try tweaking your CORS settings (if you control the third-party origin), or set crossorigin=anonymous on the script tags. For more details check out this blog post.

Let me know if that works for you 😄
