How can I catch the event exception?

Hi, I use the provider event to monitoring the wallet's balance.

prototype.on( eventType , callback )
Register a callback for any future eventType; see below for callback parameters

But sometimes since the network I get the Unhandled promise rejection: Error: Request failed with status code 403 error.
How can I catch the error in the event ? Thanks.

I've seen another issue with this as well and will look for the culprit.

It shouldn't matter too much though. I've noticed that browsers aren't as adept at realizing a promise that is actually caught at a higher level in the promise stack is handled.

Have you had this problem in v5? In v5 I've moved to using the TypeScript async/await more, which should help prevent these sorts of issues.

I think this is stale, so I'm going to close it. If you still have issues though, please re-open or create a new issue.

Thanks! :)
