Invalid object type for field "brand": the fix

Your product markup gives brand the wrong type, often Thing. Change it to Brand with a name. It's a non-critical issue, so it doesn't block your product's rich result while you fix it.

Google's help says this message means the object's type is wrong for that property. Google's product examples nest brand as a Brand with one name. Some themes and structured data apps write "@type": "Thing" instead.

Before

{
  "@context": "https://schema.org",
  "@type": "Product",
  "name": "Canvas Weekender Bag",
  "image": "https://example.com/photos/weekender-bag.jpg",
  "brand": {
    "@type": "Thing",
    "name": "Trailhead Goods"
  },
  "offers": {
    "@type": "Offer",
    "price": 89,
    "priceCurrency": "USD",
    "availability": "https://schema.org/InStock"
  }
}

After

{
  "@context": "https://schema.org",
  "@type": "Product",
  "name": "Canvas Weekender Bag",
  "image": "https://example.com/photos/weekender-bag.jpg",
  "brand": {
    "@type": "Brand",
    "name": "Trailhead Goods"
  },
  "offers": {
    "@type": "Offer",
    "price": 89,
    "priceCurrency": "USD",
    "availability": "https://schema.org/InStock"
  }
}

Give one brand name only. If the product has no brand, leave brand out instead of filling in a placeholder.

Find the code that writes it

Shopify: Dawn and Horizon use the structured_data filter, which writes Brand correctly. If you see this on Shopify, the markup comes from another theme or an app. In the theme editor's code view, search for Thing. If it isn't in the theme, check your apps.
WordPress: the theme or a schema plugin writes it. Turn plugins off one at a time on a test copy and rerun the Rich Results Test.
Custom sites: search your templates for "brand" and fix the type where it's set.

The same message on other fields

author: Google's Article docs ask for Person or Organization, never Thing.
itemReviewed: the reviewed item must be one of the types Google supports for review snippets.
<parent_node>: the problem is the object the markup hangs from, not a named field.

For the last two, see Invalid object type for field "<parent_node>".

Confirm the fix

Test a product in the Rich Results Test. Then open the report that listed the issue, click it, and click Validate fix. Google rechecks the pages as it crawls them.

Questions

Does "Invalid object type for field brand" hurt rankings?

It's a non-critical issue. The product can still show as a rich result, and the page stays indexed. Fix it when you next touch the template.

Can brand be an Organization instead of a Brand?

Schema.org allows both. Google's product docs and examples use Brand with a name, so that's the safe choice.
