custom function Roles of users not woking, nested query, prisma graphql

Question

This function isn't working properly

function getRolesOfUser(parent, args, context, info) {    

    return context.prisma.userHasRoles({user:args.user});
}

I have tried changing the paremeter in the query

{where: {user:user}}
{['User.id']:args.user}

This is the schema

type Query {
  getRolesOfUser(user: String): [UserHasRole]
}

type User {
  id: ID!
  email: String!
  roles: [UserHasRole]
}
type Role {
  id: ID!
  name: String!
}
type UserHasRole {
  id: ID!
  role: Role!
  user: User!
}

Error message:

Could not find argument user for type UserHasRole",

Expected to receive the list of roles related to a certain user

Please consider using the following code

function getRolesOfUser(parent, args, context, info) {
  return context.prisma.userHasRoles({ where: { user: { id: args.user.id } } })
}

In your schema, user is a field of UserHasRole . First select the user that meets the condition by user.id , and then filter out the UserHasRole containing user by user .
