Rails, Turbo, esbuild: TypeError: map.get is not a function

(This applies to Rails 7.1, Turbo 8.0 with esbuild and propshaft)

If you're getting a "TypeError: map.get is not a function" when navigating between pages:

Uncaught (in promise) TypeError: map.get is not a function
    at fetch (application-df30cd29ded7227ed5c827c81fa4fc9b51db518a.js:6485:20)

How to upgrade a Heroku PostgreSQL database to a new plan

How to upgrade a Heroku PostgreSQL database to a new plan

I started a project on a Hobby Dev plan (free, limit 10,000 rows), and then later needed to upgrade it to Hobby Basic ($9/month, limit 10,000,000 rows).

After assigning the new database, I had two databases attached to the application. They looked something like this:

  • HEROKU_POSTGRESQL_OLIVE (postgresql-dimensional-3321) Old, free-tier (Hobby Dev) database
