Why does S3.deleteObject not fail when the specified key doesn't exist?

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)
})
