Hi!
This feature was recently added, and I wrote about it here: Error Handling - Community Post and in more detail here: Quick Tip: Error Routing in Scenarios. Please take a look at both posts.
Additionally, a Fallback Routes feature is currently in development, which will make managing error events even easier. I believe it will be released soon.
If you simply need to ignore errors without handling them, just enable the Ignore Errors toggle!
