当我运行它的时候，代码不会在终端中产生错误!但是当我在postman中做Post Request的时候，终端会产生这个错误：

{"statusCode":500,"message":"Internal server error"}

在我的控制器中，这是@Post：

@Post('login')
    async login(
        @Body() body: LoginDto,
        @Res({passthrough: true}) response: Response
    ) {
        
        const user = await this.authService.findOneBy(body.email);

        if(!user){
            throw new BadRequestException("Email does not exist");
        }

        if(!await bcrypt.compare(body.password, user.password)){
            throw new BadRequestException("Password does not match");
        }

        const jwt =  await this.jwtService.signAsync({id: user.id});

        response.cookie('jwt', jwt, {httpOnly: true});

        return {
            user
        }
    }

这是文件loginDto：

import { IsEmail, IsNotEmpty } from "class-validator";

export class LoginDto{
    @IsNotEmpty()
    @IsEmail()
    email: string;
    @IsNotEmpty()
    password: string;
}

这是用于查找用户的@Injectable服务：

@Injectable()
export class AuthService {
    constructor(@InjectRepository(UserEntity) private readonly userRepository: Repository<UserEntity>){   
    }

    async create(user: User): Promise<User>{
        return await this.userRepository.save(user);
    }

    async findOneBy(condition): Promise<User>{
        return await this.userRepository.findOne(condition);
    }

}

这是具有TypeORM的实体

import { Exclude } from "class-transformer";
import { Column, Entity, PrimaryGeneratedColumn } from "typeorm";

@Entity()
export class UserEntity{
    @PrimaryGeneratedColumn()
    id: number;

    @Column()
    first_name: string;

    @Column()
    last_name: string;

    @Column({unique: true})
    email: string;

    @Column()
    @Exclude()
    password: string;
}

我试图找出错误whith尝试和捕捉：

try{

            if(!user){
                throw new BadRequestException("Email does not exist");
            }

            if(!await bcrypt.compare(body.password, user.password)){
                throw new BadRequestException("Password does not match");
            }

            const jwt =  await this.jwtService.signAsync({id: user.id});

            response.cookie('jwt', jwt, {httpOnly: true});

        } catch (error){

            throw error

        }

终端中显示的内容如下：
[Nest] 20445 - 25/11/2022 15：54：19错误[ExceptionsHandler]您必须提供选择条件才能查找单行。错误：您必须提供选择条件才能查找单个行。在实体管理器中。findOne（/Users/Nicolas/Desktop/NestJS/nest-auth/src/实体管理器/实体管理器。ts：1094：19）在存储库中。findOne
