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)

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.

Though Stu informs about the configuration, just to hope people encounter the same as what I did trying to put it to work on localhost. after typing awscli aws configure, as it asked you for the access ID and secret access ID, you have to at least type in something to make it work (cannot leave it blank) so that it will create config files at ~/.aws directory, where in my case I simply just typed in a for both entry, then region:localhost and output:json though i think region is really just up to you. Please help to refine my answer, at least this works out for me allowing me to continue using DynamoDB on local machine

Once configured AWS credentials are stored in a local configuration file. For windows the file can be found at

%UserProfile%\.aws\credentials

For linux the file can be found at

~/.aws/credentials

You need to have this file available. Install AWS CLI. Then to configure this file open a command line on your local machine and enter

aws configure

Details on the CLI setup are here. Details of the credentials file are here.
