Constant Summary collapse

@@vars =

@@vars cache to prevent multiple calls to Ssm Tricky note: The cache also prevents the second call to Dotenv.load from returning {} vars. Dotenv 3.0 will not return the vars if it has already been loaded in the ENV. We want this side-effect due to the new way Dotenv 3.0 works.
