AWS DynamoDB/DAX ValueError: invalid literal for int() with base 10: '//test.<chars>.dax-clusters.<region>.amazonaws.com'

Question

I understand the error but am very unsure why it is happening.

    with AmazonDaxClient.resource(
            endpoint_url='daxs://test.<chars>.dax-clusters.<region>.amazonaws.com',
            region_name='<region>'
    ) as dynamodb:
        table = dynamodb.Table('<table_name>')

        stmt = """
    for i in range(3):
        table.get_item(Key={
            'id': str(i),
            'date': str(dt + relativedelta(days=i))
        })
        """

        timer = timeit.Timer(stmt, globals={'relativedelta': relativedelta, 'dt': date.today(), 'table': table})
        result = timer.repeat(repeat, n)

        return result

I'm just trying to benchmark some read/write times to different databases that are available to me but can't get DAX to work while the standard connection to DynamoDB through boto3 seems to work fine. Any input would be very helpful

Edit: This is on a Lambda and here is the full error message:

  "errorMessage": "invalid literal for int() with base 10: '//test.<chars>.dax-clusters.<region>.amazonaws.com'",

  ]
}

Answer 1

Ended up changing the endpoint_url to test.<chars>.dax-clusters.<region>.amazonaws.com. This ended up resulting in an error telling me that the cluster endpoints were failing. I ended up having to make sure that the Lambda's security group was specified in the inbound/outbound rules for the security group that the DAX cluster was using.
