Linking is not working with latest update

[AvinashMudunuri]

@rpuls , could you take a look at this please, i was trying to extend Customer module with custom module (OTP). OTP model generation, db migrate worked well, but when created customer-otp link and executing the npx medusa db:sync-links. getting below error.

`import { model } from "@medusajs/utils";

export const Otp = model.define("otp", {
id: model.id().primaryKey(),
otp: model.text().nullable(),
otpExpiresAt: model.dateTime().nullable(),
isPhoneVerified: model.boolean().default(false),
});`

`import OtpModule from "../modules/otp";
import CustomerModule from "@medusajs/medusa/customer";
import { defineLink } from "@medusajs/framework/utils";

export default defineLink(
{
linkable: CustomerModule.linkable.customer,
isList: true,
},
OtpModule.linkable.otp
);
`

error: Invalid linkable passed for the argument

Hi @AvinashMudunuri

I am not entirely familiar with this, so I am not sure I can tell you what's wrong.

However, I think the error indicates that either CustomerModule.linkable.customer or OtpModule.linkable.otp are undefined. But both are expected to be valid linkable objects provided by their respective modules. I am not sure exactly to to debug this within your setup..

I also notice that you are still on version 2.0.4. I have updated to 2.1.3 where there have been made a some changes to the schema, and things might work a little differently - I am not sure updating will resolve your problem, but maybe it is worth updating before resolving it.

If you do update, and you need to re-seed your database, please be aware that you need an up-to-date seed script that matches the schema changes. You can find mine for version 2.1.3 here
