Issue when adding "s" at the end of HasMany association field name

[CaptainZiboo]

Issue

I found that, when using ownedOrganization or organization, it worked, but, when using ownedOrganizations for the field name, or organizations, it didn't work ! Is it normal that we cannot add an "s" add the end of the field names ? Is it because of sequelize creating files such as getUserTests ? I hope I didn't do anything wrong, if I did just tell me ! Hope anyone can help ! 👌

Actual behavior

When trying to use the instance.$create method on a model, I receive an error
See models and code snippets for model creation and instance creations below

Expected behavior

Should be creating a new organization associated to the user

Steps to reproduce

Create a model with one to many relation with HasMany field name including ( associated model name with ) "s" at the end
Exemple : Organization -> Organizations

PS : Removing the "s" at the end of "Organizations" in the user model ( see code below ) resolve the issue

Error I get in the console

        return this['create' + (0, string_1.capitalize)(propertyKey)](values, options);
                                                                     ^

I'm using these two models

import { Column, HasMany, Model, Table } from "sequelize-typescript";
import { OrganizationTest } from "./organizationtest.model";

@Table
export class UserTest extends Model {

    @Column
    name!: string

    @HasMany(() => OrganizationTest, 'owner')
    ownedOrganizations!: OrganizationTest[];

}

import { BelongsTo, Column, Model, Table } from "sequelize-typescript";
import { UserTest } from "./usertest.model";

@Table
export class OrganizationTest extends Model {

    @Column
    name!: string

    @BelongsTo(() => UserTest, 'owner')
    _owner!: UserTest

}

And here is the code to create the user and associated organization

    // Adding default admin user for testing purposes

    const user = await UserTest.create({

        username: 'admin'

    })

    Logger.info('Default admin user created !')

    const organization = await user.$create('ownedOrganizations', {
        
        name: 'My organization'
        
    })

tsconfig

    /* Language and Environment */
    "target": "es6",                                     /* Set the JavaScript language version for emitted JavaScript and include compatible library declarations. */
    // "lib": [],                                        /* Specify a set of bundled library declaration files that describe the target runtime environment. */

sequelize config

    // Creating the main database instance

    const database = new Sequelize('app', '', '', {

        storage: 'database.sqlite',
        dialect: 'sqlite',
        logging: false,
        models: [__dirname + '/../models/*.model.ts'],
        modelMatch: (filename, member) => {

            console.log(filename, member)
            return filename.substring(0, filename.indexOf('.model')) === member.toLowerCase();
        
        },
        
    });

    await database.sync({ force: true });
