Inconsistent query result: Field topics is required to return data, got `null` instead.

All data exists in the db but this still happens.

Could you provide more of your code and the full error message?
Natsuha
Natsuha•6mo ago
Sure, I'm using nextjs api and this is my code for the get request 
export const GET = async (req: Request) => {
  try {
    await connectToDatabase();

    const allTopics = await prisma.topic.findMany({
      include: { media: true, subTopics: { include: { media: true } } },
    });

    return NextResponse.json({ allTopics }, { status: 200 });
  } catch (error) {
    //error handling
    console.log(error);
    return NextResponse.json(
      { message: `Server Error ${error}` },
      { status: 500 }
    );
  } finally {
    await prisma.$disconnect();
  }
};
export const GET = async (req: Request) => {
  try {
    await connectToDatabase();

    const allTopics = await prisma.topic.findMany({
      include: { media: true, subTopics: { include: { media: true } } },
    });

    return NextResponse.json({ allTopics }, { status: 200 });
  } catch (error) {
    //error handling
    console.log(error);
    return NextResponse.json(
      { message: `Server Error ${error}` },
      { status: 500 }
    );
  } finally {
    await prisma.$disconnect();
  }
};
And this is the first part of the schema

Could you also post what your “Topic” model looks like?
Enzonaki
Enzonaki•6mo ago
Your Course model says a course only has a single Topic, you forgot a [] there, but you defined it as an array Isnt it what is causing the error?

I defined the array on the String[] on topicsid Only mediaid and authorid is supposed to be only 1 entry

I see that one topic can have many subtopics. Can a subtopic only have one "parent" topic? or many?

And this is the result I want I thought that prisma can do that for me with 
    const allCourse = await prisma.course.findMany({
      include: { author: true, topics: true },
    });
    const allCourse = await prisma.course.findMany({
      include: { author: true, topics: true },
    });
I even modified my schema to this so that the only problem I should be worried about is the array of Topics 
model Course {
  id    String @id @default(auto()) @map("_id") @db.ObjectId
  title String

  topics   Topic?    @relation(fields: [topicsId], references: [id])
  topicsId String[] @db.ObjectId
  author   User     @relation(fields: [authorId], references: [id])
  authorId String   @db.ObjectId

  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt

  Team Team[]
}

model Topic {
  id    String @id @default(auto()) @map("_id") @db.ObjectId
  title String

  subTopics SubTopic[]
  steps     Step[]
  media     Media

  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt

  Course Course[]
}
model Course {
  id    String @id @default(auto()) @map("_id") @db.ObjectId
  title String

  topics   Topic?    @relation(fields: [topicsId], references: [id])
  topicsId String[] @db.ObjectId
  author   User     @relation(fields: [authorId], references: [id])
  authorId String   @db.ObjectId

  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt

  Team Team[]
}

model Topic {
  id    String @id @default(auto()) @map("_id") @db.ObjectId
  title String

  subTopics SubTopic[]
  steps     Step[]
  media     Media

  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt

  Course Course[]
}
But still it gives me this error Moving forward I can go with this but this still leaves a bad taste in my mouth and almost half the reason that I went with prisma is so that I can avoid this boilerplate of a code @Jon Harrell please help

I'm not 100% certain, but I'm fairly sure that your schema is backwards. I see 
model Topic {
  id    String @id @default(auto()) @map("_id") @db.ObjectId
  title String

  subTopics   SubTopic @relation(fields: [subTopicsId], references: [id])
  subTopicsId String[] @db.ObjectId
.
.
.
}
model Topic {
  id    String @id @default(auto()) @map("_id") @db.ObjectId
  title String

  subTopics   SubTopic @relation(fields: [subTopicsId], references: [id])
  subTopicsId String[] @db.ObjectId
.
.
.
}
When I would expect to see 
model Topic {
  id    String @id @default(auto()) @map("_id") @db.ObjectId
  title String

  subTopics SubTopic[]
.
.
.
}

model SubTopic {
  id    String @id @default(auto()) @map("_id") @db.ObjectId
  title String

  parentTopic   Topic  @relation(fields: [parentTopicId], references: [id])
  parentTopicId String @db.ObjectId
.
.
.
}
model Topic {
  id    String @id @default(auto()) @map("_id") @db.ObjectId
  title String

  subTopics SubTopic[]
.
.
.
}

model SubTopic {
  id    String @id @default(auto()) @map("_id") @db.ObjectId
  title String

  parentTopic   Topic  @relation(fields: [parentTopicId], references: [id])
  parentTopicId String @db.ObjectId
.
.
.
}
Does that make sense?

So I should create a topic first then a subtopic? But why does authorId/author is working? The only difference is that Topic is an array

Sorry, there's a lot of different questions here. I'm trying to resolve the original error you posted: "Inconsistent query result: Field subTopics is required to return data, got null instead." The way to resolve that is to change your schema to what I suggested above. That is to say, have subTopics be an array of SubTopic on Topic and then have parentTopic and parentTopicId on SubTopic to complete the relation. Are you still having trouble with that part?

I see I get it now, I should build the schema from top to bottom I was doing it the other way around 
model User {
  id              String           @id @default(auto()) @map("_id") @db.ObjectId

model Topic {

}
model User {

  businessDetails BusinessDetails?
  role            Role

  team   Team   @relation(fields: [teamId], references: [id])
  teamId String @db.ObjectId

  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt

  Course Course[]
}

model Team {
  id   String @id @default(auto()) @map("_id") @db.ObjectId
  name String

  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
  Course    Course[]
  User      User[]
}

model Course {
  id    String @id @default(auto()) @map("_id") @db.ObjectId
  title String

  team     Team   @relation(fields: [teamId], references: [id])
  teamId   String @db.ObjectId

}

model Topic {
  id    String @id @default(auto()) @map("_id") @db.ObjectId
  title String

  course   Course @relation(fields: [courseId], references: [id])
  courseId String @db.ObjectId

  subTopics SubTopic[]
  steps     Step[]
  media     Media

  createdAt DateTime @default(now())

}

type SubTopic {
  title       String
  description String
  media       Media
}

type Media {
  name String
  type String
  link String
}

type Step {
  title String
  media Media
}

type BusinessDetails {
  subscription String
  name         String
  industryType String
  businessType String
  employeeNo   String
  position     String
}
Now this works now 
export const GET = async (req: Request) => {
  try {
    const allTopic: Topic[] = await prisma.topic.findMany({
      include: { course: { include: { team: true, author: true } } },
    });
    //logic here

    return NextResponse.json({ allTopic }, { status: 200 });
  } catch (error) {
    //error handling
    console.log(error);
    return NextResponse.json({ message: "Server Error" }, { status: 500 });
  } finally {
    await prisma.$disconnect();
  }
};
