graphqlUploadExpress missing createReadStream

[sgentile]

I have a server setup as below. I've added the graphqlUploadExpress - I'm seeing the file come through, however it's missing createReadStream ?

     async function main() {
    // Bootstrap Apollo Server
    // Use Apollo server as express middleware through 'applyMiddleware'
    const { schema } = await getBuiltMesh();
    const server = new ApolloServer({
        schema,
    });
    await server.start();

    // Bootstrap Client App
    // Next.js creates a handler that can be used as express middleware
    await nextApp.prepare();
    const app = express();
    app.get('*', nextApp.getRequestHandler());
    app.use(graphqlUploadExpress({ maxFileSize: 10000000, maxFiles: 10 }));
    server.applyMiddleware({
        app: app
    });
    await new Promise((r) => app.listen({ port: 4000 }, r));
    console.log(`🚀 Server ready at     http://localhost:4000${server.graphqlPath}`);
}

schema

scalar Upload

type File {
    filename: String!
    mimetype: String!
    encoding: String!
}

type Mutation {
    createBucket: Boolean
    uploadFile(file: Upload!): Boolean
    uploadFiles(files: [Upload]): Boolean
}

type Query {
    getFiles: Boolean
}

Did you setup the Upload scalar correctly? You've got it in your schema SDL, but what about resolvers?

Are you using an outdated version of Apollo Server that ships a conflicting older version of graphql-upload that needs to be disabled in Apollo Server options?

If you still have this issue and have determined that it is a graphql-upload bug and you’re able to provide minimal reproduction steps, we can reopen.

@jaydenseric I have same problem and investigating for last two days. Package versions; "apollo-server": "3.6.3", "apollo-server-express": "3.6.3" "graphql-upload": "13.0.0", "graphql": "15.8.0",

After upgrading Apollo Server v2 to v3, not fixed my problem. I've added express middleware and also my resolver looks like; Query: { Store: Store.getWidgets, Upload: GraphQLUpload, },

When I upload a file I got this object and createReadStream returns undefined in the file object; Other properties such as filename, mimetype and encoding are reachable. args { image: { promise: {}, file: { filename: 'istanbul.jpg', mimetype: 'image/jpeg', encoding: '7bit' } } }

yes to setting up scalar - and no to the conflicting older version
