IAM实例配置文件名称无效-Cloudformation

Question

我正在尝试通过cloudformation创建IAM角色。当我执行cloudformation模板时，出现以下错误。

Invalid IAM Instance Profile name

这是cloudformation的代码段

     Role: 
        Type: "AWS::IAM::Role"
        Properties: 
          AssumeRolePolicyDocument: 
            Version: "2012-10-17"
            Statement: 
              - 
                Effect: "Allow"
                Principal: 
                  Service: 
                    - "ec2.amazonaws.com"
                Action: 
                    - "sts:AssumeRole"
          Path: "/"
    Policies: 
        Type: "AWS::IAM::Policy"
        Properties: 
          PolicyName: "policy"
          PolicyDocument: 
            Version: "2012-10-17"
            Statement: 
              - 
                Effect: "Allow"
                Action:
                  - s3:PutObject
                  - s3:PutObjectTagging
                  - s3:GetObject
                  - s3:GetObjectTagging
                  - s3:DeleteObject
                  - s3:DeleteObjectTagging
                Resource: 
                  - arn:aws:s3:::s3-bucket/*
                  - arn:aws:s3:::s3-bucket/*
          Roles: 
            - Ref: Role
    RootInstanceProfile: 
        Type: "AWS::IAM::InstanceProfile"
        Properties: 
          Path: "/"
          Roles: 
            - Ref: "Role"

需要帮助解决这一问题。
