  prisma-client This is a non-recoverable error which probably happens when the Prisma Query Engine has a panic.

1. 使用婚姻和用户之间的 n 到 m 关系创建数据库架构

...
model User {
  id         Int        @id @default(autoincrement())
  forename   String
  lastname   String
  marriages  Marriage[]
}

model Marriage {
  id    Int    @id @default(autoincrement())
  users User[]
}

2. 迁移并启动工作室

npx prisma migrate dev --preview-feature
npx prisma studio

3. 创建 2 个用户并在他们之间建立婚姻

4. 查询用户

出现以下错误 https://github.com/prisma/prisma-client-js/issues/955

想法

似乎与prisma.user.findMany()有直接关系。

用作查询时

    Query: {
        users: (_,__,context) => {
            const pc: PrismaClient = context.prisma;
            return pc.user.findMany({ include: { marriages: true } });
        },user: async (_,args,context) => {
            const pc: PrismaClient = context.prisma;
            const users = pc.user.findUnique({ where: { id: parseInt(args.id) },include: { marriages: true } });
            return users;
        }
    }

• 失败

query {
  users {
    id
    marriages {
      id
    }
  }
}

• 作品

query {
  user(id: 1) {
    id
    marriages {
      id
    }
  }
}

另一个观察：

只有在将婚姻与 findMany 结合使用时才会发生这种情况。

    users: (_,context) => {
        const pc: PrismaClient = context.prisma;
        return pc.user.findMany({ include: { marriages: true } });
    }

如果不包含没有错误。如果它包含在 findUnique 中，它也可以工作

解决方法

上面观察到的问题似乎是最新版本中的一个错误。
