我正试图让Multipart POST与fastify Multipart一起工作，但每当我将Multipart文件发布到端点时，我的服务就会崩溃，并出现以下错误：
req.raw[kMultipart] = true
^
TypeError: Cannot set property 'Symbol(multipart)' of undefined

我是不是缺少了依赖或类似的东西？
"fastify": "^2.0.0",
"fastify-multipart": "^4.0.6",
在index.js中，这是代码：
const kMultipart = Symbol('multipart')
function setMultipart (req, payload, done) {
// nothing to do, it will be done by the Request.multipart object
req.raw[kMultipart] = true
done()
}
req.raw似乎未定义。
只有fastify-multipartv1与fastify v2 兼容
请注意，API与v3及更高版本完全不同，因此您需要更新您的fastify版本或降级您的插件并更改负载管理。
