This is my current bin/rails configuration:
#!/usr/bin/env ruby
APP_PATH = File.expand_path("../config/application", __dir__)
require_relative "../config/boot"
require "rails/commands"
I would appreciate any guidance on how to resolve this issue. Has anyone faced a similar error when deploying on Render?
