Expected null or Object but is Array on StoreAPI Product Categories

[whywilson]

Describe the bug

The return image of product categories should be null or object, but on some categories, it is an empty array.
The same issues happened on the image of /wp-json/wc/store/products/categories request.

To reproduce

Steps to reproduce the behavior:

1. Access the product category with wp-json.
2. Get the JSON content.

{
  "id": 233,
  "name": "Product Name",
  "slug": "product-name",
  "description": "Product description",
  "parent": 28,
  "count": 2,
  "image": [],   // not null or object, but array
  "review_count": 44,
  "permalink": ""
}

Expected behavior

Expected the image to be null or object.

Environment

WordPress

Core version: 6.2.2
WooCommerce version: 7.8.0

Thanks for opening this issue, @whywilson! Could you diagnose in which cases it happens? I wasn't able to reproduce, unfortunately.

For reference, the image property is generated here:

Looking forward to your reply!

Hi there,
I cannot reproduce the issues, but it happened on some specific categories.
All categories link
And search "image":[] to find more.
