我正在尝试验证用户的电子邮件是否已经存在。我正在使用Prisma Client的findUnique方法。下面是我用来尝试和完成的代码：

const userWithEmail = await prisma.user.findUnique({
    where: {
      email,
    },
  });

但是我得到了一个TypeScript错误：

No value exists in scope for the shorthand property 'email'. Either declare one or provide an initializer.ts(18004)

下面是我的schema.prisma文件：

// This is your Prisma schema file,
// learn more about it in the docs: https://pris.ly/d/prisma-schema

  provider = "prisma-client-js"
}

我的route.ts文件：

const prisma = new PrismaClient();

export async function POST(request: Request) {

  const errors: string[] = [];

  const validationSchema = [

        max: 20,

      error: "Invalid first name.",
    },
    {

    {

      error: "Invalaid password.",
    },
  ];

  validationSchema.forEach((check) => {
    if (!check.valid) {
      errors.push(check.error);
    }
  });

  if (errors.length) {
    return NextResponse.json(errors[0]);
  }

  const userWithEmail = await prisma.user.findUnique({
    where: {
      email,
    },
  });
  
  return NextResponse.json({
    response: "OK",
  });
}

我正在使用Next js 13和Prisma。我做错了什么？
