Error Faraday::ConnectionFailed suggests that you have an http request somewhere in the update chain (package_insert= setter, model validation or callbacks) that fails with this error. This is also proven by fact that simple update via console gives the same result.

Since error is reproduced by simple obj.update(package_insert: some_json), it does not relate directly to script you provided. Look into your model, especially before_*/after_*, most probably there's some after_save callback that makes an http request (as a rule of thumb - external requests from model callbacks are generally a bad idea unless you're sure how and why you do them)
