我正在尝试通过 CarrierWave 将图像上传到 S3，但不断收到 500 内部服务器错误 - Aws::S3::Errors::AccessDenied。我正在使用 ruby gem CarrierWave 来配置 AWS 和 dotenv-rails 以在 .env 文件中调用和隐藏我的凭据。看来我的代码工作正常，但我被拒绝访问我的存储桶。这是我第一次尝试将 AWS 集成到项目中，因此我的配置可能会因此而关闭。任何帮助将不胜感激。
我已经尝试重置我的访问密钥并确保我的区域设置正确。我什至更改了区域并收到一个错误提示我将其更改回正确的区域：“us-west-1”。我通过确保我可以通过 rails 控制台获取我的凭据来确保 dotenv-rails 正常工作。我还使用“byebug”在我的投资组合控制器中的更新操作中设置了一个断点，以便自己手动输入更新代码。我可以看到我正在尝试更新我的投资组合项目的新图像，但它总是回滚。

我希望这能够工作并能够访问 AWS 资源，但也许我需要为我的存储桶设置一些配置？到目前为止，AWS 文档一直难以消化。我可以使用帮助，谢谢。
