GraphQL File Update / Express not working without graphql-upload package

Hi, based on the documentation I thought we will not need any additional package for the File Upload.

We have an Express Server.

const yogaServer = createYogaServer({
    schema,
    plugins,
});

// serve graphQL
app.use(
    Config.GRAPHQL_ENDPOINT,
    (req, res, next) => {
      (req as any).identifier = v4();
      next();
    },
    // graphqlUploadExpress(),
    yogaServer,
);

Without the use of the graphqlUploadExpress middleware we are getting the following error:

400 Bad Request
{
    "data": null,
    "errors": [
        {
            "message": "Must provide query string."
        }
    ]
}
