How to store a Relation Custom Field

[rishikumarsulopa]

Hi, I am trying to relate the ProductReview and with the customField 'ProductReview'.

On ProductReview Entity side

1. I am able to create record of ProductReview using create mutation.
2. In the record, I am able to store the Product Id value in the feild ProductID (ProductID= "45").

On CustomFeild 'ProductReview' side

Problem: But I am not able to update the product's CustomField. How to update the customField

-----> in config of review.plugin.ts

config.customFields.Product.push(           
           {
                name: 'ProductReview',
                label: [{ languageCode: LanguageCode.en, value: 'Featured review' }],
                public: true,
                type: 'relation',
                list: true,
                nullable: true,
                entity: ProductReview,
            })

------> in service

all three methods not not working

  const updatedReviews = [newEntity.id];
  await this.customFieldRelationService.updateRelations(
            ctx,
            Product,
            { customFields: { ProductReview: updatedReviews } },
            product
        );

        await this.productService.update(ctx, {
            id: productId,
            customFields: {
                ProductReview: newEntity.id
            },
        });

  await this.customFieldRelationService.updateRelations(
            ctx,
            Product,
            { customFields: { ProductReview: newEntity.id } },
            product
        );
