// Using callbacks
s3.headObject(params, function (err, metadata) {  
  if (err && err.name === 'NotFound') {  
    // Handle no object on cloud here  
  } else if (err) {
    // Handle other errors here....
  } else {  
    s3.getSignedUrl('getObject', params, callback);  
    // Do stuff with signedUrl
  }
});

// Using async/await
try {
  await s3.headObject(params).promise();
  const signedUrl = s3.getSignedUrl('getObject', params);
  // Do stuff with signedUrl
} catch (error) {
  if (error.name === 'NotFound') { // Note with v3 AWS-SDK use error.code
    // Handle no object on cloud here...
  } else {
    // Handle other errors here....
  }
