AWS DynamoDB Missing credentials in config in local dev environment

Question

My colleague successfully perform the following code showing the table without setting the credentials in local environment, but when i conduct it it shows such error on my local machine. Please help.

Please find my codes below:

Controller:

    AWS.config.update({
        region: 'localhost',
        endpoint: new AWS.Endpoint('http://localhost:8008'),
    })
    var params = {
        TableName: 'history',
        KeySchema: [{
            AttributeName: 'b_id',
            KeyType: 'HASH'
        },{
            AttributeName: 'e_id',
            KeyType: 'RANGE'
        }],
        AttributeDefinitions: [{
            AttributeName: 'b_id',
            AttributeType: 'S',
        },{
            AttributeName: 'e_id',
            AttributeType: 'N',
        }],
        ProvisionedThroughput: { // required provisioned throughput for the table
            ReadCapacityUnits: 1, 
            WriteCapacityUnits: 1, 
        },
    }
    response.implicitEnd = false
    AWS.query('history',params, function(err, data){
        if(err) console.log(err)
        else  response.json(data)
    })

Error: connect EHOSTUNREACH 169.254.169.254:80 is a failure to connect to the EC2 instance metadata service, which is expected since you are not running this code inside EC2. The most likely explanation is that your colleague does indeed have credentials configured in their local environment. — Michael - sqlbot
Thanks for your input @Michael-sqlbot, however how do i configure my local environment? is it like what Siu's answer and comments stated below? I failed to execute the last step because I couldn't find my .bash_profile, even after i touch it it still doesnt work (sorry for my lack of bash knowledge) — warmjaijai
it may also be just .profile. If you have sudo access, you can sudo pip install awscli and you don't have to redefine the path. — Michael - sqlbot
ya i think i installed it but it doesn't work still, error message remains: awc: command not found — warmjaijai

This is what's working for me

AWS.config.update({
  region: 'us-east-1',
  accessKeyId: 'xxxx',
  secretAccessKey: 'xxxx',
  endpoint: 'http://localhost:8000'
});

const dynamodb = new AWS.DynamoDB()
const dynamoDbClient = new AWS.DynamoDB.DocumentClient();

The accessKeyId and secretAccessKey does not need to be real values.
