使用AWSPowerShell.NetCore时不存在AWS S3存储桶

Question

我正在尝试移植我们的C＃控制台应用程序，该应用程序使用AWSPowerShell.NetCore进行部署到Powershell Core。

但是，当我尝试将对象写入S3时，它说指定的存储桶不存在。

Write-S3Object -BucketName "my.bucket.name" `
    -Key "myfile.txt" `
    -File "./myfile.txt" `
    -CannedACLName public-read `
    -AccessKey "my-aws-key" `
    -SecretKey "my-aws-secret" `
    -EndpointUrl "https://special-endpoint-url" `
    -Region "us-west-2"

但是C＃中相同的代码（至少据我所知）有效。

var config = new AmazonS3Config
{
  ServiceURL = "https://special-endpoint-url",
  RegionEndpoint = RegionEndpoint.USWest2
};

var creds = new BasicAWSCredentials("my-aws-key", "my-aws-secret");

using (var s3Client = new AmazonS3Client(creds , config))
{
  var putObjectRequest = new PutObjectRequest()
  {
    BucketName = "my.bucket.name",
    CannedACL = S3CannedACL.PublicRead,
    FilePath = "./myfile.txt",
    Key = "myfile.txt"
  };

  await s3Client.PutObjectAsync(putObjectRequest);
}

我已经仔细检查了存储桶的名称，但是在这里没有发现错误。
