Javascript Prisma更新功能因类型不正确而失败

我用的是Prisma2。变异函数如下所示：

const updateUserProfileDetails = async (
  inputValues, ctx: { session?: SessionContext } = {}
) => {
  const profile = await db.user.update({
    where: { id: ctx.session!.userId },
    data: {
      profile: {
        update: {
          aboutMe: "this is a random message for about me.",  // type error is displayed here
          location: "London, UK", // same type error here
          profession: "rubber duck", // same type error here
        },
      },
    },
  });
  return profile;
};

model User {
  id             Int       @default(autoincrement()) @id
  createdAt      DateTime  @default(now())
  updatedAt      DateTime  @updatedAt
  firstName      String?
  lastName       String?
  email          String    @unique
  hashedPassword String?
  role           String    @default("user")
  sessions       Session[]
  profile        Profile?
}

model Profile {
  id                 Int       @default(autoincrement()) @id
  aboutMe            String?
  location           String?
  profession         String?
  user               User      @relation(fields:[userId], references: [id])
  userId             Int
}

然而，在关于我、

位置

、

专业

道具的

上，typescript却在尖叫：

类型“string”不可分配给类型“NullableStringFieldUpdateOperationsInput |未定义”。ts（2322）

相关架构如下所示：

const updateUserProfileDetails = async (
  inputValues, ctx: { session?: SessionContext } = {}
) => {
  const profile = await db.user.update({
    where: { id: ctx.session!.userId },
    data: {
      profile: {
        update: {
          aboutMe: "this is a random message for about me.",  // type error is displayed here
          location: "London, UK", // same type error here
          profession: "rubber duck", // same type error here
        },
      },
    },
  });
  return profile;
};

model User {
  id             Int       @default(autoincrement()) @id
  createdAt      DateTime  @default(now())
  updatedAt      DateTime  @updatedAt
  firstName      String?
  lastName       String?
  email          String    @unique
  hashedPassword String?
  role           String    @default("user")
  sessions       Session[]
  profile        Profile?
}

model Profile {
  id                 Int       @default(autoincrement()) @id
  aboutMe            String?
  location           String?
  profession         String?
  user               User      @relation(fields:[userId], references: [id])
  userId             Int
}

版本：

@prisma/cli: 2.6.0 => 2.6.0 
@prisma/client: 2.6.0 => 2.6.0 

我无法找到（在文件夹中搜索）NullableStringFieldUpdateOperationsInput的定义。我做错了什么？
能否将
@prisma/cli
和
@prisma/client
更新为2.7.1？它在最新版本中运行良好。我试过了，TS在这里没有抱怨，查询也很好
