Right now the docs on https://render.com/docs/deploy-phoenix do not work. As discussed in the Slack chat, you have to manually switch the node-sass dependency as a workaround for recent changes in the Render node environment.
Would love to see this updated, if nothing else to learn if this is the “official” way to run Elixir on Render.
This makes me wonder - how are environment upgrades like this tested or announced by the Render team? It is really frustrating to have my deployment break because of an unannounced upgrade. While I generally like Render more than Heroku, this is something that Heroku would never do.
