Unable to deploy static website using CircleCI

Question

Summary: I'm trying to automate the deployment of a static site (gatsby) to an S3 bucket using a CircleCI orb, but I keep getting the following error:

#!/bin/bash -eo pipefail aws configure set aws_access_key_id
$AWS_ACCESS_KEY_ID
--profile default The config profile (*******) could not be found Exited with code exit status 255 CircleCI received exit code 255

I already checked my environment variable for AWS_ACCESS_KEY_ID in an AWS context I setup in CircleCI. I searched for some answers on the circleci official forum, I tried the adviced offered here https://discuss.circleci.com/t/you-must-specify-a-region-you-can-also-configure-your-region-by-running-aws-configure-exited-with-code-255/14392, but still no progress fixing the issue. I'd appreciate if anyone could give me a hand.

Also, here's my CircleCI config.yml file

version: 2.1

      - image: circleci/node:12.19.1
