Update catalog item via patchListingsItem

[BarnetMichal]

I would like to edit the bullet_point of a product that has already been added to the catalog. It was added via POST_PRODUCT_DATA. I would like to edit it via patchListingsItem. When I try this I get the error '"The field 'value' for the attribute 'brand' does not have enough values. The required minimum is '1' value(s)."' In the Product schema, brand/value is marked as "editable": false. So do I have to first create a listing via putListingsItem even if the product already exists in the catalog and then call patchListingsItem on it?

@BarnetMichal What does your PATCH request look like? (Can you paste a copy of the payload?) Typically, you would only see errors related to the brand attribute on a PATCH request if you provided an empty brand attribute as part of the PATCH request. A request like the following should work (replacing values with your own, such as product type, language, and values):

{
  "productType":"LUGGAGE",
  "patches":[
    {
      "op":"replace",
      "path":"/attributes/bullet_point",
      "value":[
        {
          "value":"Bullet Point 1",
          "language_tag":"en_US"
        },
        {
          "value":"Bullet Point 2",
          "language_tag":"en_US"
        }
      ]
    }
  ]
}

Yes, I only sent the brand attribute with language_tag and market_id. Omitting the brand attribute helped, thanks!
