出现错误——The authorization header is malformed; the region 'us-east-1' is wrong; expecting 'ap-south-1' （服务名：Amazon S3; 状态码：400; 错误码：AuthorizationHeaderMalformed）。

【以下的回答经过翻译处理】 Are you sure it's getBucketLocation() returning the error rather than something using its output that's getting tripped up by the null? 对于除us-east-1之外的所有区域，getBucketLocation() 都会返回类似于“af-south-1”的区域ID。而对于us-east-1，它会返回null。这种情况可能是由于您使用getBucketLocation()的输出时遇到了空值。
