最大节点 header 大小与 mocha + superagent

Question

我正在运行测试并收到以下错误：

Error: Request Header Fields Too Large
      at Test.Request.callback (node_modules/superagent/lib/node/index.js:626:17)
      at IncomingMessage.<anonymous> (node_modules/superagent/lib/node/index.js:795:18)
      at IncomingMessage.emit (domain.js:475:12)

我正在使用 VS Code 调试配置运行：

{
            "type": "node",
            "request": "launch",
            "name": "Mocha",
            "skipFiles": [
                "<node_internals>/**"
            ],
            "program": "${workspaceFolder}/node_modules/.bin/mocha",
            "runtimeArgs": [
                "--max-http-header-size=1048576"
            ],
            "args": [
                "--no-timeouts", "test/test1.js"
            ]
}

所以我希望 http header 选项已经设置但我仍然收到错误。 superagent 有自己的配置还是我做错了什么？
