AWS/S3 - "Missing credentials in config"

Specifically, the error I’m getting is
“S3 sync failed: TimeoutError: Missing credentials in config”

This is what the job looks like in the config file:

  - image: circleci/node:8.2
working_directory: ~/[repo]
  - checkout
  - run: sudo rm -rf node_modules
  - run: npm install
  - run: sudo apt-get install awscli
  - run:
      command: |
        aws configure set aws_access_key_id $DEV_AWS_KEY
        aws configure set aws_secret_access_key $DEV_AWS_SECRET
        aws configure set default.region us-west-2
        node run publish-dev
        aws cloudfront create-invalidation --cli-input-json "{\"DistributionId\":\"E320VZN6YT3QIW\",\"InvalidationBatch\":{\"Paths\":{\"Quantity\":1,\"Items\":[\"/*\"]},\"CallerReference\":\"$(date +%s)\"}}"
        cat ./coverage/ | ./node_modules/.bin/codacy-coverage

The environment variables under Build Settings in circleci look like this:

This was working fine in Circle 1, and I think environment variables are handled differently now somehow, but I can’t figure out from either the AWS docs or CircleCI docs what I need to do differently. Also, the back end (java/mvn) is working just fine and it references them exactly the same way in the config file

Since you mentioned 1.0, can you add #aws to the end of your project settings page and make sure you don’t have any old AWS creds then need to be deleted?
