How to upgrade to v10?

That snippet doesn’t work anymore: https://github.com/jaydenseric/graphql-upload#class-graphqlupload

In the resolve method, everything is undefined:

const { filename, mimetype, createReadStream } = await image

console.log(filename, mimetype, createReadStream)
// undefined undefined undefined

How are we supposed to upgrade from v9?

It looks like image is now a dedicated class with properties resolve, reject, promise & file but according to the doc, most of them should only be utilized by processRequest..

Using .promise seems to solve the issue:

const { filename, mimetype, createReadStream } = await image.promise

But .file seems to be the resolved promise:

const { filename, mimetype, createReadStream } = image.file

Am I right? Which one is the way to go?

Regarding your original issue, it looks like maybe the GraphQLUpload scalar is not coming from graphql-upload v10? Or the other way around, perhaps the old middlware/processRequest is running with the new scalar - could this be because you are Apollo Server?

You’re right we used a custom type for the upload and not the one shipped with your lib. Replacing it with GraphQLUpload fixed the issue.

Thanks for all the explanations and sorry for bothering you about that
