Ruby bundle console is not loading aws shared credentials from ~/.aws/credentials

Question

How can I load aws credentials to ruby if I use bundler console.

Scenario:

I have the following code in samplefile.rb and aws credentials in ~/.aws/credentials

require 'aws-sdk-core'
require 'aws-sdk-s3'
require 'json'

class Publisher
    def listBuckets
        profile_name = 'AWSConsumer'
        region = "us-east-1"
        s3 = Aws::S3::Client.new(profile: profile_name, region:region)
        resp = s3.list_buckets
        resp.buckets.each do |bucket|
        puts bucket.name
    end
end
Publisher.new.listBuckets

This is working fine by taking the shared credentials when I use $ruby samplefile.rb

but when I execute the same using $bundle exec bin/console

Getting missing credentials .

missing credentials, provide credentials with one of the following options: - :access_key_id and :secret_access_key - :credentials - :credentials_provider

As per the AWS documentation, its should load the shared credentials for ruby.
