当我通过 graphql-playground 创建我的所有者时，它工作正常，但我的测试失败并回复我“body.data.createOwner 未定义”，没有数据。

// owner.e2e.spec.ts
describe('Owner test (e2e)', () => {
    let app: INestApplication;

    beforeAll(async () => {
        const moduleRef = await Test.createTestingModule({
            imports: [
                GraphQLModule.forRoot({
                    autoSchemaFile: join(process.cwd(), 'src/schema.gql'),
                }),
                OwnerModule,
                DatabaseModule
            ]
        }).compile();
        app = moduleRef.createNestApplication();
        await app.init();
    });

    afterAll(async () => {
        await app.close();
    })

    const createOwnerQuery = `
           mutation createOwner($OwnerInput: OwnerInput!) {
            createOwner(ownerInput: $OwnerInput) {
              _id
              name
              firstname
              email
              password
              firstsub
              expsub
              createdAt
              updatedAt
            }
          }
    `;
   
    let id: string = '';

    it('createOwner', () => {
        return request(app.getHttpServer())
            .post('/graphql')
            .send({
                operationName: 'createOwner',
                variables: {
                   OwnerInput: {
                        name: 'adar',
                        firstname: 'adar',
                        email: 'adar@test.com',
                        password: 'testing',
                        firstsub: '2020-08-14',
                        expsub: '2020-07-13'
                    }
                },
                query: createOwnerQuery,
            })
            .expect(({ body }) => {
                const data = body.data.createOwner <-- test fail at this line
                id = data._id
                expect(data.name).toBe(owner.name)
                expect(data.email).toBe(owner.email)
                expect(data.firstsub).toBe(owner.firstsub)
            })
            .expect(200)
    })

// Output terminal

我的问题来自 CLI 插件，它自动生成可为空的 Graphql 字段，而没有将 @Field 装饰器放在我的 ObjectType 中。

巢的创造者就这个问题给出了一个窍门。

但这对我不起作用，所以我只是在我的模型@ObjectType() 中的所有属性中添加了“@Field”装饰器。
