My application.yml file is as follows:

KEYS: ["xxxxxx", "yyyyyy", "zzzzzz"]

When I run figaro heroku:set

I receive this error:

.rbenv/versions/2.4.0/lib/ruby/gems/2.4.0/gems/figaro-1.1.1/lib/figaro/cli/heroku_set.rb:7:in `system': no implicit conversion of Integer into String (TypeError)

Anyone know how I should format arrays in application.yml?

Heroku only allows plain strings as environmental variables. If you still want to pass an array, you need to join it into string and then split in your code.

# application.yml
KEYS: "xxxxxx,yyyyyy,zzzzzz"

And then in your application code you can use it like

(ENV["KEYS"] || "").split(",")
