Moved environment variables outside function to avoid redundancy.

[kefaslungu]

Removed setting of environment variables from inside function, since it's only required once.

Since the environment variables will only be set once, it's better outside the function since it can be called as many times as necessary, but it's only required to set the key and region once.
