error: cannot query across one-to-many for property members

I am new with typeorm and I face trouble with a OneToMany relationship. I have a Person entity which contains a @OnetoMany relationship to a Member entity and a @ManyToOne relationship to a Fare entity. I can post a new Person without problem but I get an error when I update an existing Person with the following body:

{"firstName":"john","lastName":"doe","fareId": 1} The error is the following:

(node:699940) UnhandledPromiseRejectionWarning: Error: Cannot query across one-to-many for property members Here is my Person entity:

import { Entity, Column, ManyToOne, OneToMany, PrimaryGeneratedColumn } from "typeorm";

import { Fare, Member } from "./";

@Entity()
export class Person {
    @PrimaryGeneratedColumn()
    id: number;

    @Column({
        unique: false,
        nullable: false
    })
    firstName: string;

    @Column({
        unique: false,
        nullable: false
    })
    lastName: string;

    @Column({
        unique: false,
        nullable: true
    })
    address: string;

    @Column({
        unique: false,
        nullable: true
    })
    phone: string;

    @Column({
        unique: false,
        nullable: true
    })
    email: string;

    @OneToMany(() => Member, member => member.person)
    members: Member[];

    @ManyToOne(() => Fare, fare => fare.persons)
    fare: Fare
}

Here is the update part of my controller:

router.put('/persons/:id', async (req: Request, res: Response) => {
    const id = +req['params']['id'];
    const person = await this._personService.readOne(id);
    if (!person) {
        res.status(400).send('Person not found')
    }

    const { lastName, firstName, address, email, phone, fareId } = req['body'];
    if (fareId) {
        const fare = await this._fareService.readOne(fareId);
        if (!fare) {
            res.status(400).send('Fare not found')
        } else {
            person.fare = fare;
        }
    }

    person.lastName = lastName ? lastName : person.lastName;
    person.firstName = firstName ? firstName : person.firstName;
    person.address = address ? address : person.address;
    person.email = email ? email : person.email;
    person.phone = phone ? phone : person.phone;

    const updatedPerson = await this._personService.update(person,id);
    res.send(updatedPerson);
});

and here is the update part of my Person service:

public update = async (person: Person, id: number) => {
    const updatedPerson = await this._personRepository.update(id, person);
    return updatedPerson;
}

would you know what is wrong with my code ?

Thanks for the quick answer. So, there is no way to pass around that problem ? Should I consider to change of ORM ?

to which ORM you switched? Sequelize is good but no update with relations out of box Prisma has strange model definition Typeorm not have select some fields from relations and filter by relations and always push you querybuilder

No normal ORM for NodeJS

Remains to see what is MicroORM

many thanks for the hint. I will give a try with relationId.
