GraphQLUpload scalar implementation

[vekonylaszlo]

Hey👋

I'm trying to create a file upload mutation based on the ApolloGraphQL documentation.
I can't figure out, how should I map the GraphQLUpload to the Upload scalar.

In the builder file, I added a new scalar like this:

Scalars: {
    ...
    Upload: { Input: Upload; Output: Upload; }
  };

And then i tried to add the GraphQLUpload like this:

builder.addScalarType("Upload", GraphQLUpload, {});

But I get an error message:
Argument of type 'GraphQLScalarType' is not assignable to parameter of type 'GraphQLScalarType<unknown, unknown>'. Type 'GraphQLScalarType' is missing the following properties from type 'GraphQLScalarType<unknown, unknown>': specifiedByURL, [Symbol.toStringTag]

Can you give me a hint on how should I solve this?
Thank you very much!

My guess is you have two copies of graphql in your dependency graph.

This issue is probably related: graphql/graphql-js#3156

I would highly recommend using resolutions (if you are using yarn or pnpm) to ensure you only have 1 version of graphql
