If you are using thoughtbot’s Paperclip gem, make sure you have it properly configured for Solano CI. The most common problem is having the Paperclip command_path option set incorrectly.
In your config/initializers/paperclip.rb, make sure you set the
/usr/bin. For instance:
# Set path to ImageMagick installation when using Solano CI if ENV.member?('TDDIUM') Paperclip.options[:command_path] = "/usr/bin" end
