Using the AWS SDK for Node, why do I not get an error when trying to delete an object that doesn't exist (i.e. the S3 key is wrong)?

If I specify a non-existent bucket on the other hand, an error is produced.

If you consider the following Node program, the Key parameter lists a key which doesn't exist in the bucket, yet the error argument to the callback is null:

var aws = require('aws-sdk')



function getSetting(name) {

  var value = process.env[name]

  if (value == null) {

    throw new Error('You must set the environment variable ' + name)

  }

  return value

}



var s3Client = new aws.S3({

  accessKeyId: getSetting('AWSACCESSKEYID'),

  secretAccessKey: getSetting('AWSSECRETACCESSKEY'),

  region: getSetting('AWSREGION'),

  params: {

    Bucket: getSetting('S3BUCKET'),

  },

})

picturePath = 'nothing/here'

s3Client.deleteObject({

  Key: picturePath,

}, function (err, data) {

  console.log('Delete object callback:', err)

})
