Create Row with relation

[Notaduck]

Hi again, I was wondering if you can help me out here.

I'm trying to create a new row which has a relation to a customer/contact, I can see the the metadata name is iu_customerid, but when i add the contactId from a contact as the iu_customerid do I get the following error

@Notaduck hi!

It would be more clear to me if you could post an approximate code you are trying to run. Thank you!

I'm simply trying to create a policy entity.

          const response = await this.dynamicsWebApi.create<DynamicsPolicyDTO[]>({
            collection: DynamicsCollections.POLICIES,
            data: chunk,
            returnRepresentation: true,
          });

the policy have a relation to a customer which either can be a contact or an account. Looking at the entity I can see it has a iu_customerid for the customer, and going one step further I can see this is the values

But when I try to give it iu_customerid_value do I get the following error:

I just had to read MS's documentation, sorry. This was the answer to my question

  @Expose()
  @Transform(({ obj }: PolicyWithQuote): string => `/contacts(${obj.customerId})`)// obj.customerId, { toClassOnly: true })
  "iu_customerid_contact@odata.bind": string; // Field for customer relationship
