GraphQL mutation type missing in the response

Question

I built in my GraphQL API a DeleteUserMutation which should allow me to delete a user and have a response with a message but on the return, I'm getting an error:

SError: ⨯ Unable to compile TypeScript:
src/graphql/mutations/user/delete-user.ts:21:9 - error TS2740: Type '{ responseCode: number; message: string; user: any; }' is missing the following properties from type 'User': id, name, last_name, email, and 4 more.

21         return response;
           ~~~~~~~~~~~~~~~~

I tried to achieve that when a User is deleted and success in the response I see the message from my type DeleteUserresponse

export const DeleteUserResponse = gql`
    type DeleteUserResponse {
        responseCode: Number!
        message: String!
        user: User
    }
`;

The mutation should delete the user and if success shows the success values and if not shows the opposite and I tried in this way:

import { getRepository } from 'typeorm';
import { Entities } from '../../../entities/entities';

export const deleteUserMutation = {
    async deleteUser(_, { id }): Promise<typeof user> {
        const response = {
            responseCode: 500,
            message: 'Error, user not deleted',
            user: null,
        };

        const repository = getRepository(Entities.user);
        const user = await repository.findOne({ id });

        if (user && repository.delete({ id })) {
            response.responseCode = 200;
            response.message = 'User deleted successfully';
            response.user = user;
        }

        return response;
    },
};

But this above doesn't work and cannot understand what is the issue as I'm a newbie in GraphQL. The error suggests the types are missing but I tried to play around adding and removing types but that error is not going away.

What is the issue in my code and how to fix it.

Answer 1

输入Mutation {deleteUserMutation（input：{}）：Respone}输入Respone {responseCode：Number！消息：String！user：User}请使用上面的模式

Answer 2

I want to show my solution to my problem as based on comments I read on my question.

I changed the typeof as follow and that fixed the issue:

Promise<typeof deleteUserMutation>

Full code:

import { getRepository } from 'typeorm';
import { Entities } from '../../../entities/entities';

export const deleteUserMutation = {
    async deleteUser(_, { id }): Promise<typeof deleteUserMutation> {
        const response = {
            responseCode: 500,
            message: 'Error, user not deleted',
            user: null,
        };

        const repository = getRepository(Entities.user);
        const user = await repository.findOne({ id });

        if (user && repository.delete({ id })) {
            response.responseCode = 200;
            response.message = 'User deleted successfully';
            response.user = user;
        }

        return response;
    },
};
