createReadStream()引发RangeError:上传文件时超出最大调用堆栈大小 [英] createReadStream() throwing RangeError: Maximum call stack size exceeded when uploading file

问题描述

我正在尝试使用Apollo Server的 Upload 标量直接将文件发送到S3.我的架构:

I am trying to use Apollo Server's Upload scalar to send files to S3 directly. My schema:

const { gql } = require('apollo-server-express')

module.exports = gql`

extend type Mutation {
  createPicture(
    name: String!
    picture: Upload!
  ): Picture!
}

type Picture {
  name: String!
  picture: String!
}
`

解析器:

const { combineResolvers } = require('graphql-resolvers')
const isAuthenticated = require('./auth')
const { uploadPhoto } = require('../services/picture')

module.exports = {
  Mutation: {
    createPicture: combineResolvers(
      isAuthenticated,
      async (
        parent,
        { name, picture = null },
        { models, me }
      ) => {
        const { createReadStream, filename, mimetype, encoding } = await picture
        // Does not get past this line
        const stream = createReadStream()

        uploadPhoto(stream, filename)

        const pictureModel = models.Picture.create({
           name,
           picture
        })
        return pictureModel
      }
    )
  }
}

但是我的代码错误是这样的:

But my code errors like this:

internal/util.js:55
  function deprecated(...args) {
                     ^

注意:我确定图像发送正确，因为文件名是正确的

Note: I am sure the image was sent correctly, as filename is correct

推荐答案

原来是 graphql-up 中的这个错误.降级到节点12并修复(在那里列出的解决方案对我没有帮助)

Turns out it was this bug in graphql-upload. Downgraded to node 12 and it's fixed (solution listed there did not help me)
