Currently, raven-js(browser side. not sentry-php. rESNT/resources/raven/raven.js) on Sentry Extension is out of date.
The version that sentry extension uses is released 7 years ago(v1.1.16 according to sentry report. Doesn't appears on npmjs.org but v1.1.17 is released on 3/8/2015.)
Even, raven-js is old sdk which last release was 3 years ago. it replaced with @sentry/browser. We should migrate to that.
