Nestjs GraphQL query not running [duplicate] - graphql

Question

This question already has an answer here:
Problem with multiple graphql resolver implementations in nestjs
(1 answer)
Closed 4 years ago.
I have the following schema:
type User {
id: String!
email: String
}
type Mutation {
createUser(input: CreateUserDto!): CreateUserResponseDto!
}
type Query {
user(id: Int!): User
}
input CreateUserDto {
email: String!
password: String!
}
type CreateUserResponseDto {
id: String!
}
And I have the following resolver:
import {Args, Mutation, Resolver} from '#nestjs/graphql';
import {UserService} from '../service/user.service';
import {CreateUserDto, CreateUserResponseDto, UserDto} from '../controller/dto/user.dto';
import {Query} from '#nestjs/common';
#Resolver('User')
export class UserResolver {
constructor(private readonly userService: UserService) {
}
#Mutation()
async createUser(#Args('input') userDto: CreateUserDto): Promise<CreateUserResponseDto> {
const userEntity = await this.userService.createUser(userDto);
return {
id: userEntity.id,
};
}
#Query('user')
async getUser(#Args('id') id: number): Promise<UserDto> {
const userEntity = await this.userService.findUserById(id);
return {
id: userEntity.id,
email: userEntity.email,
};
}
}
When running the following query:
{
user(id: 2) {
email
}
}
I am getting the following response:
{
"data": {
"user": null
}
}
And when trying to debug it seems like the call never reaches the resolver.
When trying to run the mutation, all works as expected.
What did I miss?

You're using the wrong Query decorator. You've imported it from #nestjs/common instead of #nestjs/graphql.
It's confusing that they both have the same name and if you're using your IDE to automatically fix imports for you it's possible to pull in the wrong one.
