[React] bunch of ReferenceError tslib_1__default is not defined

[spondbob]

I have a simple Sentry setup in my React app where I add init right before render()

Sentry.init({
  dsn: config.SENTRY_DSN
})

Now Sentry reports bunch of ReferenceError to tslib_1__default which seems come from after I installed the package. See screenshot.

Did I miss something with the setup or is there a bug here? I have @sentry/browser@4.3.3 installed.

Upgrade to recent 4.3.4 seems fixed the issue.
