Pasting any string longer than a couple hundred characters into a Heroku rails console takes forever. The more characters are pasted, the slower it goes, letter by letter. Is there a way to make this run at a reasonable speed?

This is a problem with Ruby's 2.7's default multi-line pasting in irb. Here's how to resolve it.
$ heroku run -a my_app_name bash
$ echo 'IRB.conf[:USE_MULTILINE] = false' > ~/.irbrc
$ bin/rails c
