邮递员无法使用宁静的Web服务删除请求

Question

当我尝试通过从邮递员中选择Jraw -JSON类型来将Delete请求作为子文件发送时。我收到以下错误。我从互联网上进行了详细搜索，发现了类似的错误，但没有任何解决方案。您可以在下面看到“删除”请求，并在发送GET请求后获得结果。

我对POSTMAN的删除请求：

{"MyCfgTestService.TEST_ENUM"}

错误：

2020-02-11 21:20:37.109  WARN [-,906c2c05c5f88216,906c2c05c5f88216,false] 87038 --- [nio-    8014-exec-1] .m.m.a.ExceptionHandlerExceptionResolver : Resolved exception caused by Handler  execution: org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Cannot deserialize instance of `java.util.ArrayList` out of START_OBJECT token; nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `java.util.ArrayList` out of START_OBJECT token

我从邮递员那里获取请求：

 {
"name": "test",
"profiles": [
    "native"
],
"label": "beta",
"version": null,
"state": null,
"propertySources": [
    {
        "name": "file:////Users/alperkopuz/config-repo/test.yaml",
        "source": {
            "MyCfgTestService.TEST_NUMBER": 1,
            "MyCfgTestService.TEST_TEXT": "default",
            "MyCfgTestService.TEST_TIMESTAMP": "\n0\n",
            "MyCfgTestService.TEST_ENUM": "One",
            "MyCfgTestService.TEST_BOOLEAN": false,
            "MyCfgTestService.TEST_TEXTAREA": "line1\nline2\tblablabla\n",
            "MyCfgTestService.TEST_PASSWORD": "secret"
        }
    }
]

}
