json - 带有用于仪表板主体的嵌入式 JSON 字符串的 AWS Cloudformation YAML 文件

Question

尝试在使用 CloudFormation 时将我们的仪表板制作为代码。使用 YML 文件中嵌入的 JSON 字符串验证模板时出现错误。它的“SEARCH('{AWS/EC2,InstanceId)”字段存在问题，表示这些是无效字符串。我已经通过 JSON Linter 运行它并且工作正常。我还使用 JSON 很好地部署了 CloudWatch 仪表板控制台。

问题:

有没有办法将此部分包装为 YML 文件中 CloudFormation 的字符串，这样它就不会被 JSON 字符串内容绊倒？
