@nertzy I think there are some dependency issues related to the recent Ruby 3.x release. To update your Rollbar.js without waiting for this to merge, in your config/initializers/rollbar.rb, add or update js_options

config.js_options = {
  rollbarJsUrl: "https://cdn.rollbar.com/rollbarjs/refs/tags/v2.21.0/rollbar.min.js"
}

The snippet will use the specified version.

For the build break, when this merges you should be able to rebase master to fix. #1027
