Verification of Environment Variables

For this implementation to work satisfactorily, you must check if these environment variables are added:

PLAID_CLIENT_ID = <YourClientID> 
PLAID_SECRET_KEY = <YourSecretKey>
PLAID_ENV = <YourEnviroment> 
PLAID_CLIENT_NAME = <YourApplicationName>

ENCRYPTION_SECRET_KEY= <yourEncriptionSecretKey>
ENCRYPTION_IV= <yourEncryptionIV>
