Grafana TwinMaker Scene 插件显示“Load 3D Scene failed with Network Failure”

Question

【以下的问题经过翻译处理】 你好！当我从TwinMaker尝试将场景加载到Grafana时，如何修复“Load 3D Scene failed with Network Failure”的问题？

Answer

【以下的回答经过翻译处理】 存储3D模型文件的Amazon S3存储桶缺少[CORS policies](https://docs.aws.amazon.com/AmazonS3/latest/userguide/cors.html)。
要修复此问题，请将以下CORS策略添加到Amazon S3存储桶中：

```
[
    {
        "AllowedHeaders": [
            "*"
        ],
        "AllowedMethods": [
            "GET",
            "PUT",
            "POST",
            "DELETE",
            "HEAD"
        ],
        "AllowedOrigins": [
            "*"
        ],
        "ExposeHeaders": [
            "ETag"
        ]
    }
]
```
