// Here's another example environment source file. Unlike defaultEnv.js, this one exports an array of
// functions where each function returns an object (or a Promise resolving to an object) containing
// some key/value pairs. Again, the returned object values MUST be strings as they will eventually
// become lambda environment variables, and at this time AWS only supports strings.
//
// The functions will be executed in order starting at index 0, where each function's key-values will be merged with the former. 
// Latter values may overwrite values from previously-executed functions if multiple functions return references to the same key. The
// resulting merge of all key-value pairs across all functions will then be sent as the environment variables to your Lambda.
