WSO2中使用的Restful端点未接收任何请求有效负载

Question

我试图在WSO2中调用两个休息端点。来自第一个端点的响应用于构建json有效负载，以作为发布请求发送到第二个端点。 问题是第二个端点没有看到有效负载，因此错误消息“请求正文中提供的JSON语法无效：com.google.gson.stream.MalformedJsonException：使用JsonReader.setLenient（true）接受显示第1行第54列的格式错误的JSON。

当我启用wirelogs时，我发现post请求被发送到第二个端点但没有有效负载。但令我惊讶的是，当我记录它时，有效载荷不是空的。

如果你能帮帮我，我将不胜感激。

请在下面找到我的模型摘录
