It is outdated. I’m facing the same issue and I found that Raven is now a legacy client and it is not recommended for new projects. You can find more information from the official documentation at sentry.io: https://docs.sentry.io/clients/javascript/
I personally found that, even though I’m using the up to date versions of the other dependencies, I used the version of Raven mentioned in the video. I then used the script version of sentry’s line. This still connected and reported fine to sentry.
