# This is just a test, not the final variables used in the config
# This just here to fail a build and deploy fast if there's a config problem
# so we put the file in a different location to be sure we don't mix up

# **NOTE**: If you update the environment variables, don't forget to update them
# in ./launch.sh too which is what's used in production
