I'm getting "Object captured as exception with keys" events, what do they mean?

Issue

I'm getting unknown events with title "Object captured as exception with keys:..." with no stack trace and little information.

• All SDKs

Resolution

These kind of events happens when a non-error object is thrown or manually sent to Sentry. For example:

const nonErrorObject = {
   keys:"lost",
   foo:"bar",
   details:"unremarkable"
}

Sentry.captureException(nonErrorObject)
//or
throw nonErrorObject

This is an expected behaviour and the only way to prevent it is by finding where the non-error object is being thrown/raised. 

You can filter these events with ignoreErrors (for other filters, please check the dedicated filtering docs for your SDK):

ignoreErrors:["Object captured as exception"]
