I am coding a CRUD API built in TypeScript and TypeGoose.
I get an error saying,
CannotDetermineGraphQLTypeError: Cannot determine GraphQL output type for '_id' of 'User' class. Is the value, that is used as its TS type or explicit type, decorated with a proper decorator or is it a proper output value?
I have a User entity.
import { Field, ObjectType } from 'type-graphql';
import { ObjectId } from 'mongodb';
import { prop as Property, getModelForClass } from '@typegoose/typegoose';
@ObjectType()
export class User {
@Field()
readonly _id: ObjectId;
@Field()
@Property({ required: true })
email: string;
@Field({ nullable: true })
@Property()
nickname?: string;
@Property({ required: true })
password: string;
constructor(email: string, password: string) {
this.email = email;
this.password = password;
}
}
export const UserModel = getModelForClass(User);
And this is how my query resolver looks like.
@Query(() => [User])
async users() {
const users = await UserModel.find();
console.log(users);
return users;
}
How can I solve this? It seems to be like TypeGraphQL doesn't understand what the MongoDB ID is?
Im not sure about this, but maybe ObjectId.toString() help you. MongoDB doc about ObjectId.toString()
