UnhandledRejection: Non-Error promise rejection captured with value: Timeout

Package + Version

@sentry/browser@5.13.0

Description

We are receiving a high volume of exceptions that follow the same signature. They occur across all pages, and in all sorts of places with seemingly no discernible pattern. It occurs across all browsers with frequency roughly the same as usage.

UnhandledRejection Non-Error promise rejection captured with value: Timeout

In all cases the Exception is missing. There is no stack trace or additional information.

I’m pretty certain this is originating from third-party code, but without more information to go on I’ve been unable to pin this down.

I’m opening this as a bug because it feels like Sentry should be reporting additional information to help pinpoint the source of the error.

There is an existing issue for this that has been closed without any resolution: https://github.com/getsentry/sentry-javascript/issues/2210

The issue lies exactly there: https://www.gstatic.com/recaptcha/releases/P6KLRNy7h3K160ZmYNUOAce7/recaptcha__en.js

c.reject("Timeout ("+y+")")

or

H((vn.delete(P),"Timeout")

tl;dr - they reject with a primitive value, but should with new Error("timeout").

In this case, your best solution until they fix it is to ignore this kind of errors.

Sentry.init({
  beforeSend(event, hint) {
    if (hint.originalException === "Timeout") return null;
    return event;
  }
});
