Why aren’t you using our [Discourse official Standard Installation](https://meta.discourse.org/t/discourse-official-standard-installation/142537) for a production instance?

Essentially you need to install `brotli` package at Heroku. I don’t know how to do it, but probably there’s some build-pack allowing you to do that, or you can build your own. In my case (Ubuntu 18.04@[Github Actions](https://github.com/pricemate-com/discourse-sentry/runs/714619150?check_suite_focus=true)) I’ve [fixed](https://github.com/pricemate-com/discourse-sentry/blob/master/.github/workflows/lint.yml#L60) it with `sudo apt-get -yqq install brotli`.
