Receiving resource not found error when creating commerce product through headless API

Issue

• When creating a product using headless API. After creating it, the product status shows 'Approved'; however, when searching for the product or clicking the product to open it, that shows the resource not found error on the UI.
• Steps to reproduce:
  1. Start Liferay DXP 7.4 U90.
  2. Create a new site using the 'Minimum template'
  3. Now navigate to Applications > Workflow > Process Builder. Click on the 'Configuration' tab.
  4. Assign the 'Single approver workflow' to 'Commerce Product'.
  5. Now, navigate to Global Menu > Commerce > Catalogs. Create a demo catalog.
  6. Then go to localhost:8080/o/api > /o/headless-commerce-admin-catalog/v1.0/products.
  7. Method: POST and add the below request body. Please change the catalog ID with which we have created in the 4th step:

  {
  "active": true,
  "catalogId": 44330,
  "categories": [],
  "productType": "virtual",
  "defaultSku": "BC20247534542387",
  "name": {
  "en_US": "Product"},
  "description": {
  "en_US": "test product description"},
  "externalReferenceCode":"10141299",
  "expirationDate": "2024-11-12T12:03:45.043Z",
  "neverExpire": false,
  "skus": [
  {
  "discontinued": false,
  "externalReferenceCode": "10141299",
  "published": true,
  "price": 0,
  "promoPrice": 0,
  "purchasable": true,
  "sku": "BC20247534542387",
  "skuOptions": null
  }]}

  8. Check the product; it is in the 'Approved' state, and then navigate to the created site, find the created product, and click on this.
  Observed behavior: It is showing the error on the UI.
  Expected behavior: As this product is in an approved state, it should show the product on the UI.

Environment

• Liferay DXP 7.4

Resolution

• The reported issue is not a bug, this is considered to be the correct behavior of the API when working with an enabled workflow.
• To achieve the requirement, the user can create a custom workflow and custom headless roles to be used in this scenario, so the product skips the approval step if it is created by headless API through a certain user.
• Skipping the approval process for products created via API in a custom approval workflow. User can follow the document Single Approver Workflow: how to bypass for admin role
