Trouble accessing AWS Rekognition facial analysis using ``paws`` package

This is not a data analysis issue, so I don't have a data to reproduce.

I installed the paws package from this Github page to extract facial features (i.e., smile) via Amazon Rekognition. I am doing it as a part of a study to test performance across Microsoft Azure and Face++. By the way, I replaced "AccessKeyHere" and "SecretKeyHere" with appropriate security IDs.

library(paws)

Sys.setenv(
  AWS_ACCESS_KEY_ID = "AccessKeyHere",
  AWS_SECRET_ACCESS_KEY = "SecretKeyHere",
  AWS_REGION = "us-east-1"
)

ec2 <- paws::ec2()

resp <- ec2$run_instances(
  ImageId = "ami-f973ab84",
  InstanceType = "t2.micro",
  KeyName = "default",
  MinCount = 1,
  MaxCount = 1,
  TagSpecifications = list(
    list(
      ResourceType = "instance",
      Tags = list(
        list(Key = "webserver", Value = "production")
      )
    )
  )
)

Unfortunately, I get this error:

Error: InvalidKeyPair.NotFound: The key pair 'default' does not exist

I tried following through the Setting Up Credentials document in the Github page without success.

The results I want would look something along the lines of this (taken directly from Amazon demo):

If I could advance to this stage, it would be fantanstic. But it would be even nicer if the extracted data could look consistent with my Microsoft Azure results:

The error is with this line:

KeyName = "default",

It is referring to an Amazon EC2 Key Pair that should be attached to the Amazon EC2 instance. However, there is no keypair named default. Therefore, it fails.

To fix it, instead of default you should use the name of a Keypair that has been created. You can see a list of keypairs in the EC2 management console. You could also remove this line (without specifying a KeyName), but then you would not be able to login to the instance.
