In your "webpack.dev.config.js" replace `fs.write(fd, buf, 0, buf.length, 0, function (err, written, buffer){});` with `fs.write(fd, buf, function(err, written, buffer) {});` same goes to production webpack config

In your "webpack.dev.config.js" replace `fs.write(fd, buf, 0, buf.length, 0, function (err, written, buffer){});` with `fs.write(fd, buf, function(err, written, buffer) {});` same goes to production webpack config

I also having the same problem, and i found the solutions. Change: ``` ``` to ``` ```

just replace your graphql/userLoaders.js line 8 `(fieldName: string, schema: Object): Function =>` to `(fieldName: string, schema: Object) =>`
