Error: Unable to create a POST object policy without a bucket, region, and credentials

Question

我正在尝试使用 AWS javascript sdk，
生成 PresignedPost URL 我收到以下错误 -

Error: Unable to create a POST object policy without a bucket, region, and credentials

我在本地配置了具有 S3 访问权限的 AWS 凭证，
在代码中，我在创建 S3 客户端时设置区域，
将存储桶名称作为参数传递给客户端方法时。

以下是代码片段-

const AWS = require('aws-sdk');
let util = require('util');

let s3Client = new AWS.S3({
    region: 'us-east-1'
});

let postSignedUrl = async () => {

    try {
        let postSigningParams = {
            Expires: 60,
            Bucket: "some-bucket-name,
            Conditions: [["content-length-range", 100, 10000000]],
            Fields: {
                key: 'test/image.jpg'
            }
        }

        let s3createPresignedPost = util.promisify(s3Client.createPresignedPost).bind(s3Client);
        let postSignedUrl = await s3createPresignedPost('putObject',postSigningParams);

        console.log('postSigningParams => ', postSignedUrl);
    } catch (error) {
        console.error(error);
    }
}

postSignedUrl();

我尝试了以下方法，但没有用 -

AWS.config.update({region:'us-east-1'});
let s3Client = new AWS.S3();

类似的 AWS S3 sdk 方法有效 -

let presignedUrl = async () => {

    let signingParams = {
        Bucket: 'some-bucket-name',
        Key: 'test/image.jpg',
        Expires: 60
    }

    let s3GetSignedUrl = util.promisify(s3Client.getSignedUrl).bind(s3Client);
    let signedUrl = await s3GetSignedUrl('putObject',signingParams);

    console.log('signedUrl => ', signedUrl);
}

犯了一个愚蠢的错误，
在 createPresignedPost 方法调用中错误地传入 putObject 作为参数

let postSignedUrl = await s3createPresignedPost('putObject',postSigningParams);

应该只是-

let postSignedUrl = await s3createPresignedPost(postSigningParams);
