Function fromEnv

Create a credential provider that reads credentials from the following environment variables:

• AWS_ACCESS_KEY_ID - The access key for your AWS account.
• AWS_SECRET_ACCESS_KEY - The secret key for your AWS account.
• AWS_SESSION_TOKEN - The session key for your AWS account. This is only needed when you are using temporary credentials.
• AWS_CREDENTIAL_EXPIRATION - The expiration time of the credentials contained in the environment variables described above. This value must be in a format compatible with the ISO-8601 standard and is only needed when you are using temporary credentials.

If either the AWS_ACCESS_KEY_ID or AWS_SECRET_ACCESS_KEY environment variable is not set or contains a falsy value, the promise returned by the fromEnv function will be rejected.
