为什么发送多个POST请求失败[JSON-server]

Question

我通过RESTful约定使用JSON服务器多次发送POST请求。但这破坏了我的JSON服务器。有人知道这是什么原因吗？

代码的小部分：

axios.post(`http://localhost:3005/intersections/`, {
                    title: intersection
                }).catch(function(error){
                    console.log(error)
                })
                if (intersection) {
                    axios.post(`http://localhost:3004/points/`, {
                        title: intersection.geometry.coordinates
                    }).catch(function(error){
                        console.log(error)
                    })
                }

错误：
