I have following issue:

In IOS build process it happens that a request is made to our Sentry server, and if Sentry server is temporary down (in our case it happens often), an error throws:

-error: API request failed
  caused by: sentry reported an error: gateway timeout (http status: 504)
Add --log-level=[info|debug] or export SENTRY_LOG_LEVEL=[info|debug] to see more output.

I would like to allow CLI failure because it currently makes CI/CD pipeline to fail.
In @sentry/webpack-plugin there is an option to override default error handler and allow CLI failure, is there a similar option in @sentry/react-native as well?
* source: https://github.com/getsentry/sentry-webpack-plugin#options (errorHandler)

Steps to reproduce:

• Add Sentry to newly created app and initialize it Sentry.init(..)
• Close/stop Sentry server
• Try to build IOS project

Actual result:

Build fails because Sentry server isn't responsive.

Expected result:

Allow CLI failures as in case when there are issues connecting to Sentry server (5xx error)
