Please can you help me to host Guttenberg-search on heroku?

Hi, For covid-19 https://github.com/opencovid19-fr/data, we need a search engine that can help to quickly find some volunteers who have registered themself into a googleform. As soon as I have an app, I will a manually transfert volunteers from a googlesheet file to a database. I found your app, it looks perfect (ty!) and I began to work on it. But i failed to implement on heroku. I first tried to upload a modified version I built by following step by step yours instructions(https://blog.patricktriest.com/text-search-docker-elasticsearch/), without success. Then I tried to upload the original code onto my heroku (https://devcenter.heroku.com/articles/local-development-with-docker-compose#pushing-your-containers-to-heroku), but it fails too : https://dataagainstcovid-search.herokuapp.com/ I made only 1 modification : changing 8080:80 to 80:80, in docker compose, because heroku ask for service that runs on 80 (AFAIK : https://stackoverflow.com/questions/28706180/setting-the-port-for-node-js-server-on-heroku).

I really know bad ES. Would u mind to indicate what should be done IYO to build Guttenberg-search on heroku? Thank you in advance for any help or advice.
