TypeScript error: The expected type comes from property 'data' which is declared here on type... | Prisma | Page 1

I'm getting this error while using Prisma Client 5.0.0:

Type '{ number: number; type: "User" | "Message"; guildId: string; threadId: string; messageId: string | undefined; channelId: string | undefined; author: { connectOrCreate: { where: { userId: string; }; create: { ...; }; }; }; target: { ...; }; trackedContent: { ...; }; }' is not assignable to type '(Without<ReportCreateInput, ReportUncheckedCreateInput> & ReportUncheckedCreateInput) | (Without<...> & ReportCreateInput)'.
  Types of property 'author' are incompatible.
    Type '{ connectOrCreate: { where: { userId: string; }; create: { userId: string; guildId: string; }; }; }' is not assignable to type 'undefined'.ts(2322)

Code:

await prisma.report.create({
    data: {
      number,
      type: message ? "Message" : "User",
      guildId,
      threadId: forumPost.id,
      messageId: message?.id,
      channelId: message?.channel.id,
      trackedContent: { createMany: { data: trackedContent } },

      author: {
        connectOrCreate: { where: { userId: author.id }, create: { userId: author.id, guildId } },
      },
      target: {
        connectOrCreate: { where: { userId: target.id }, create: { userId: target.id, guildId } },
      },
    },
  });

Schema:

model GuildMember {
  userId String @id @map("user_id")

  guild   Guild  @relation(fields: [guildId], references: [guildId])
  guildId String

  // Reports are the reports that the user has made
  reports Report[] @relation("reports")
  // History is the reports that the user has been reported for
  history Report[] @relation("history")

  createdTrackedContent TrackedContent[]

  @@map("guild_member")
}

model Report {
  id        String   @id @default(cuid()) @map("report_id")
  createdAt DateTime @default(now()) @map("created_at")
  number    Int

  guild    Guild      @relation(fields: [guildId], references: [guildId])
  guildId  String     @map("guild_id")

  author   GuildMember @relation(name: "reports", fields: [authorId], references: [userId])
  authorId String      @map("author_id")

  target   GuildMember @relation(name: "history", fields: [targetId], references: [userId])
  targetId String      @map("target_id")

  messageId   String?  @map("message_id")
  channelId   String?  @map("channel_id")
  fieldValues String[] @map("field_values")

  trackedContent TrackedContent[]

  @@unique([number, guildId])
  @@map("report")
}

It works when I use authorId: ... + targetId: ... and having another function for upserting the GuildMembers. However, I would like to do this in one function call and am wondering why this error is happening, especially with the error mentioning undefined.

Basically, TS does not recognise author and target as valid keys in data: {}, although authorId and targetId is able to be used.
