perl - Perl PAWS SelectObjectContent - “前提条件失败”

Question

当我尝试运行时收到“Precondition Failed”错误：

my $obj = $s3->SelectObjectContent(
    Bucket              => 'MyBucket',
    Expression          => 'SELECT * FROM s3object s',
    ExpressionType      => 'SQL',
    InputSerialization  => {
        JSON => {
            Type => 'LINES'
        }
    },
    Key                 => 'MyKey',
    OutputSerialization => {
        JSON => {}
    } );

我关注了 https://metacpan.org/pod/Paws::S3::SelectObjectContent#RequestProgress-=%3E-Paws::S3::RequestProgress

我已经使用我的存储桶和密钥成功调用了“GetObject”，因此这些不对错误负责。
