Property 'fetchPage' does not exist on type.

[tyazhelomov]

I use typescript v. 4.5.3, node.js v 14.17.4 and bookshelf + postgres
I have this code:
export async function getTransactions(userId: number, page: number): Promise {
try {
let transactions = await new TariffsTransactions()
.where({"user_id": userId})
.orderBy("created_at", 'DESC')
.fetchPage({ page });
if (transactions){
transactions = (transactions).serialize();
return transactions;
}
else{
return {};
}
}
catch (err: any){
return err;
}
}

and a get error: TS2339: Property 'fetchPage' does not exist on type 'TariffsTransactions'.

It's model:

import bookshelf from '../config/bookshelf';

import Table from '../resources/enums/Table';
import TariffsFunctions from './TariffsFunctions';
import Users from './User';

class TariffsTransactions extends bookshelf.Model {
get requireFetch(): boolean {
return false;
}

get tableName(): string {
return Table.TARIFFS_TRANSACTIONS;
}

get hasTimestamps(): boolean {
return true;
}
tarrifsFunctions(): any {
return this.hasMany(TariffsFunctions, 'id');
}
users(): any {
return this.hasMany(Users, 'id');
}
}

export default TariffsTransactions;

How i can fix this error?
