How to test graphql + apollo server for upload file mutation using postman?

Question

I using apollo server, and have this mutation :

mutation {
  updateData(
    file1: fileOne,
    file2: fileTwo,
    file3: fileThree,
    payload: {
      id: "7e3583b4-5673-48df-a3cf-44a4ec33f0e1"
    }
  ){
    isSuccess
    error
    data
  }
}

I want to test it using postman, because i didnt find any clue test it using graphql playground.

I already find how to test graphql from postman, but it doesn't contains information about file upload. graphql postman

I have an idea from apollo-upload-client to post using multipart-formdata but it still fail.

please help how to test graphql with apollo server for upload file mutation using postman?

thanks

Are you fixed on Postman or can you try another REST client? I know how to do this using Insomnia - it is not a very pretty solution but it has worked for me. I vaguely recall having trouble achieving this on Postman altogether due to some bug or limitation in Postman. — Avius
i found some clue from internet and it works, using postman formdata must add multer on server. — yozawiratama
@Avius Can u pls help me with insomina ? how to do it there ? — Sushilzzz

I need to understand about how file upload works in node js (because I use nodejs ini this case)

I install multer for file upload middleware using nodejs and expressjs, if you use other framework or programming language, just try adjust it
In postman I use formdata
