CORS，S3和CloudFront配置

每当我尝试将文件发布到S3存储桶时，都会收到以下错误消息：

POST https://api.*.com/sermon 413
Access to XMLHttpRequest at 'https://api*.com/sermon' from origin 'https://*.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

我的S3 ELB存储桶配置如下（用于https://api.*.com/sermon）：

我的Cloudfront设置如下（针对https://api.*.com/sermon）：

我还设置了CloudFront Origin Response触发器作为Lambda函数：

'use strict';

// If the response lacks a Vary: header, fix it in a CloudFront Origin Response trigger.

exports.handler = (event, context, callback) => {
    const response = event.Records[0].cf.response;
    const headers = response.headers;

    if (!headers['vary'])
    {
        headers['vary'] = [
            { key: 'Vary', value: 'Access-Control-Request-Headers' },
            { key: 'Vary', value: 'Access-Control-Request-Method' },
            { key: 'Vary', value: 'Origin' },
        ];
    }
    callback(null, response);
};

HTTP状态：

我有什么想念的吗？
