回送存储组件请求中止

Question

这是前端文件上传的代码。

axios.post(
            'http://localhost:3333/api/Containers/mycontainer/upload',
            {
                file: files[0]
            },
            {
                headers: {
                    Accept: 'multipart/form-data'
                }
            }
        );

当我在浏览器控制台中发布文件时，出现此消息

POST http://localhost:3333/api/Containers/mycontainer/upload net::ERR_EMPTY_RESPONSE

在服务器中出现此日志

Error: Request aborted
    at IncomingMessage.<anonymous> (/Users/hayksafaryan/Projects/other/ev/node_modules/formidable/lib/incoming_form.js:122:19)
    at IncomingMessage.emit (events.js:182:13)
    at abortIncoming (_http_server.js:444:9)
    at socketOnClose (_http_server.js:437:3)
    at Socket.emit (events.js:187:15)
    at TCP._handle.close (net.js:616:12)

    at TCP._handle.close (net.js:616:12)

在后端，我遵循了本指南 https://loopback.io/doc/en/lb2/Storage-component.html

这是数据源

"fileStorage": {
    "name": "fileStorage",
    "connector": "loopback-component-storage",
    "provider": "filesystem",
    "root": "./fileStorage",
    "maxFileSize": "10485760"
  }

使用回送3
