duplicate react error

[nightnei]

I use componentDidCatch to send error, like in the new documentation. But I receive 2 errors: one is from componentDidCatch and another is sent from somewhere another place. Can I disable autosend errors?

componentDidCatch(error, errorInfo) {
      this.setState({ error });
      Sentry.configureScope(scope => {
        Object.keys(errorInfo).forEach(key => {
          scope.setExtra(key, errorInfo[key]);
        });
      });
      Sentry.captureException(error);
}

Hey @nightnei – this is a client library issue, so you should open this on getsentry/sentry-javascript.

I think it'd be helpful if you could share the trace. Given that they're grouping separately, yes, it seems it's being caught elsewhere (maybe bubbling all the way up to onerror).

@nightnei do you use development mode by any chance?

https://docs.sentry.io/clients/javascript/integrations/react/

One important thing to note about the behavior of error boundaries in development mode is that React will rethrow errors they catch. This will result in errors being reported twice to Sentry with the above setup, but this won’t occur in your production build.
