Meteor：回调传递给非Meteor库

Question

我在流星和简单中使用restivus：json-routes作为中间件。

在中间件功能中，一旦收到文件数据，集合上的插入方法就会失败。

错误：Error: Meteor code must always run within a Fiber. Try wrapping callbacks that you pass to non-Meteor libraries with Meteor.bindEnvironment.

JsonRoutes.Middleware.use((request, response, next) => {
    if (request.url === "/upload" && request.method === "POST") {
            let fileInfo, data;


            request.on("data", (chunks) => {
                    data += chunks;
                    console.log("data in ");
            });

            request.on("end", () => {

                    res = someCollection.insert({test: 'value'});
                    console.log(res);
                    if (res) next();
            });
    }
    else {
            next();
    }
});
