媒体转换服务上的 AWS IAM 角色策略问题 [无法打开输入文件 [无法读取数据:AssumeRole 失败]]]

AWS IAM Role Policy Issue on Media Convert Service [ Cannot open input file [Failed to read data: AssumeRole failed]]]

我正在为 AWS IAM 角色策略而苦苦挣扎,我正在学习 Lambda 函数的教程,以便在上传新文件时从 s3 存储桶事件中读取并将其发送到 AWS MediaConvert 以转换视频文件。 Lambda 函数能够在测试中从 s3 读取,但它在 MediaConvert 的作业失败。

我已经为角色设置了策略并提供了内联策略,但我仍然无法让它工作。

PolicySummary

确保分配给 MediaConvert 作业的 IAM 角色具有信任 MediaConvert 的信任策略

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "",
      "Effect": "Allow",
      "Principal": {
        "Service": "mediaconvert.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}

这通常在您在管理控制台中创建 IAM 角色并将 select MediaConvert 作为服务时自动生成。
