Comment (by fudxtrpj14):

 It seems like the warning you're encountering is related to the structure
 of the taxonomy parameter in the REST API request. The `include_children`
 parameter is a great addition for handling nested terms, but it appears
 that there might be an issue with how it's being processed internally.

 To address this warning and ensure proper functionality, you can adjust
 the way you structure your REST API request. Instead of directly nesting
 the `include_children` parameter within the `categories` object, consider
 placing it alongside the `terms` array. Here's an example:

 ```javascript
 const query = {
     categories: {
         terms: [3, 5, 7],
     },
     include_children: true,
 };
 ```

 By moving `include_children` outside the `categories` object, you maintain
 a flat structure for the taxonomy parameters, which should align with the
 expectations of the `class-wp.php` processing.

 This adjustment ensures that the `include_children` parameter is not
 treated as part of the `categories` taxonomy parameter array, potentially
 resolving the "Array to string conversion" warning you've encountered.

 Make sure to test this modification in your specific use case and
 environment to confirm that it resolves the warning and doesn't introduce
 any unintended side effects. If the issue persists, you might want to
 check for updates in the WordPress core or related documentation for any
 changes in handling these parameters.
