错误：DBClusterInstanceClass不支持DB engine aurora-mysql | Cloudformation。

【以下的问题经过翻译处理】 你好团队，

我创建了一个用于aurora-mysql8.0的CloudFormation模板。但是在运行模板时，我遇到了错误：DBClusterInstanceClass不支持DB引擎aurora-mysql。我不确定是否需要从模板中删除此选项，因为那样我将无法设置DBClusterInstance类型。

模板如下：

‘’‘ Parameters: DatabaseName: Default: MyDatabase Description: The database name Type: String MinLength: '1' MaxLength: '64' AllowedPattern: '[a-zA-Z][a-zA-Z0-9]*' ConstraintDescription: must begin with a letter and contain only alphanumeric characters.

谢谢。
