Prisma graphql updateNode mutation

Question

I'm trying to setup the updateNode mutation in graphql with Prisma running on GraphQL-yoga server. Here's the error I'm receiving when I try to run the mutation:

"Variable \"$_v0_data\" got invalid value { data: { name: \"Test\" }, where: { id: \"cjqulnr0yftuh0a71sdkek697\" } }; Field \"data\" is not defined by type CocktailUpdateInput.\nVariable \"$_v0_data\" got invalid value { data: { name: \"Test\" }, where: { id: \"cjqulnr0yftuh0a71sdkek697\" } }; Field \"where\" is not defined by type CocktailUpdateInput."

Here's my mutation resolver:

const Mutation = {
  async updateCocktail(parent, args, ctx, info) {
    const data = { ...args };
    delete data.id;
    const where = {id: args.id};
    return await ctx.db.mutation.updateCocktail({ data, where }, info);
  },
}

datamodel.prisma:

type Cocktail {
  id: ID! @unique
  name: String!
  info: String
  glass: Glass
  ingredients: [Ingredient]
  steps: [Step]
}

schema.graphql

type Mutation {
  updateCocktail(data: CocktailUpdateInput!, where: CocktailWhereUniqueInput!): Cocktail
}

and finally here's what I'm trying to execute in playground:

mutation{
  updateCocktail(
    where: {id: "cjqulnr0y0tuh0a71sdkek697"},
    data: {
      name: "Test"
    }
  ){
    id
    name
  }
}

If I read your resolver correctly, you resolvers does the following:

Take the args and put them in data (without the id)
Take the id in the args and put it in where

But, in the playground, you give the following args:

args = {
  where: {id: "cjqulnr0y0tuh0a71sdkek697"},
  data: {
    name: "Test"
  }
}

They are already well formed! Which means your resolvers is gonna do the step as follow and build the following variables:

data = {
  where: {id: "cjqulnr0y0tuh0a71sdkek697"},
  data: {
    name: "Test"
  }
}

where = { id: null }

You can fix this two ways:

1/ Don't rebuild data and where in the resolvers and just pass the args down to prisma

2/ When calling your mutations, give it the args as follow:

updateCocktail(id: "abc", name: "Test") {...}
