Run aws configure list .

If profile is not set, then you need to set it along with others (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_DEFAULT_REGION):

export AWS_PROFILE=default

export AWS_ACCESS_KEY_ID=A*******

export AWS_SECRET_ACCESS_KEY=***

export AWS_DEFAULT_REGION=us-east-1 (Note: Change for appropriate region)
