Xml 在reult中配置JSON输出的DSS错误

我的DSS服务有问题，我找不到任何问题的答案，这让我很沮丧。我的服务有一个sqlserver数据源，并将我的输出映射为JSON，当使用内容类型application/JSON测试服务时，我得到一个错误。下面是dss碳记录。我以前遇到过这种情况，解决方案是启用转义不可打印字符，但是即使启用了它，我仍然会遇到下面的错误。请帮忙

这也发生在我身上， 解决方案是检查我在“输出映射”中添加的json是否是正确的json

复制粘贴您的“输出映射”JSON，然后查看格式是否正确

您是否正确。我的输出映射上有一个格式错误，这就是为什么我得到无效的启动错误。非常感谢你！伟大的德鲁，我很高兴能帮上忙。请你投票赞成我的答案，谢谢
