Products without variants don't show up in the admin panel

[BitPatty]

Describe the bug
Products created via the createProduct mutation in the admin api don't show up in the admin panel unless a product variant is created.

To Reproduce
Steps to reproduce the behavior:

1. Create a product with the createProduct mutation in the admin-api
2. Go to the admin panel
3. The product is not listed but accessible by specifying the id in the url (though the manage variants view is broken)

Expected behavior
It should be possible to create a product without a variant or else require a product variant in the createProduct mutation.

Environment (please complete the following information):

• @vendure/core version: 0.18.0
• Nodejs version 14.15.1
• Database (mysql/postgres etc): mysql

Additional context
Test Product 123 not showing up in the admin panel:

Broken variant management in the admin panel after accessing the product via its id (/admin/catalog/products/:id)

The underlying reason for this is that the product list view uses the search query to get the list of products/variants to display. This in turn in based on the search index, which only knows about ProductVariants.

I'm not yet sure how to solve this, though I agree it needs fixing.

[Ayzrian]

Can't we add a "default" product variant to the product when we create it?

[michaelbromley]

@Ayzrian Yes, this could be a solution, I'd have to explore the implications of this.

I've created a few products and product variants using the graphql mutations createProduct and createProductVariants from the admin-api playground.
These products are successfully created and I can see them when I query through the graphql query for products, but they don't show up in the admin UI.
I've also rebuilt the search index in the admin ui and also ensured that the enabled property on all the products and productVariants are set to true.

Versions from my package.json file below:

"dependencies": {
    "@pinelab/vendure-plugin-google-storage-assets": "^1.2.1",
    "@vendure/admin-ui-plugin": "3.0.0",
    "@vendure/asset-server-plugin": "3.0.0",

  },

    "concurrently": "8.2.2",
    "ts-node": "^10.9.2",
    "typescript": "^5.5.4"
  }

I recently updated to version 3.0.0 from version 2.1

Am I missing something? Can someone please help?

Hi, since v2.x we no longer use the search query to power the admin ui product list. So the search index is definitely not the issue here.

My first idea is that if you are using multiple channels, maybe they got created in a different channel that what you expect?

Ah you were absolutely correct @michaelbromley. I had created a channel for this particular project but all the graphql mutations had been creating products in the Default Channel. Checked that and sure enough, all the products and facets show up in the admin UI.

Thanks!
