prisma foreign key constraint error after merging user & admin into 1 table

I was handling authorization like this that i make a model for users and model for admin and each one has an email and password but now i am trying to refactor my code by merging users and admin into 1 table and handle auths like below

model all_users {
  id       String   @id @default(uuid())
  name     String
  email    String   @unique(map: "user_email_key")
  password String
  role     String
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt

  user user?
  admin       admin?      
}

model user{
    id           String?
    alluserId String?     @unique
    user         all_users ?     @relation(fields: [userId], references: [id])
   votes     votes[]
}

model admin{
    id           String?
    alluserId String?    @unique
    user         all_users ?     @relation(fields: [userId], references: [id])
     votes     votes[]
}

model votes{
    id                  String        @id @default(uuid())
    votes          Json?
    user user @relation(fields: [userId], references: [alluserId])
    userId String
    admin        admin    @relation(fields: [adminId], references: [alluserId])
    adminId      String
    createdAt           DateTime  @default(now())
    updatedAt           DateTime  @updatedAt

    @@index([entrepreneurId], name: "index_votes")
}

but now when I try to make npx prisma db push so I can use votes i always get this error insert or update on table "votes" violates foreign key constraint "votes_userId_fkey" 0: sql_schema_connector::apply_migration::migration_step I am not sure why this happens , therefor prisma has no errors.

How can I api useQuery when calling a function?

 const { data: allData, isLoading } = api.admin.limitAccess.useQuery(
    {first,rows},
    { refetchOnWindowFocus: false }

I am using useQuery to fetch first , rows depends on a pagination but I have a button to click so I can download all the data from the query so I want to use it like this

  const exportCSV = async () => {
    try {
      const response = await api.admin.limitAccess.useQuery({ first: 0, rows: totalRecords });
      setAllData(response?.data);
      tableRef?.current?.exportCSV();
    } catch (error) {
      console.error("Error exporting CSV:", error);
    }
  };

but when I use something like this I get an error , why I cannot use the api inside a function ?

Error exporting CSV: Error: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
