Issue completing basic commands for Spaces using s3 AWS SDK on NodeJS

Using the docs here, I attempted to get a list of available spaces. However, I get the following error:

NotImplemented: Server does not support one or more requested headers. Please see https://de
velopers.digitalocean.com/documentation/spaces/#aws-s3-compatibility

Code is below:

const AWS = require("aws-sdk");

// set to use the digital ocean s3
AWS.config.credentials = new AWS.SharedIniFileCredentials({
  profile: "digitalocean"
});

// configure endpoints for DO spaces
const spacesEndpoint = new AWS.Endpoint("nyc3.digitaloceanspaces.com");
const s3 = new AWS.S3({
  endpoint: spacesEndpoint
});

// list buckets
s3.listBuckets({}, function(err, data) {
  if (err) console.log(err, err.stack);
  else {
    data["Buckets"].forEach(function(space) {
      console.log(space["Name"]);
    });
  }
});

// list the available buckets
s3.listObjects({ Bucket: "my-experimental-expressjs-piece" }, function(
  err,
  data
) {
  if (err) {
    console.log(err);
  } else {
    console.log(data);
  }
});

Any idea what might be going wrong?
