I am seeing php error in log:
PHP Warning: Invalid argument supplied for foreach() in /var/web/site/public_html/wp-content/plugins/woocommerce/packages/woocommerce-blocks/src/BlockTypes/ProductCategories.php on line 182

This appears to be line 182: foreach ( $tree as $category ) {
and these are 183-186:
if ( ! empty( $categories_by_parent[ ‘cat-‘ . $category->term_id ] ) ) {
$category->children = $this->fill_category_children( $categories_by_parent[ ‘cat-‘ . $category->term_id ], $categories_by_parent );
}
}

This is the whole section:
```
/**
	 * Build hierarchical tree of categories.
	 *
	 * @param array $categories List of terms.
	 * @return array
	 */
	protected function build_category_tree( $categories ) {
		$categories_by_parent = [];

		foreach ( $categories as $category ) {
			if ( ! isset( $categories_by_parent[ 'cat-' . $category->parent ] ) ) {
				$categories_by_parent[ 'cat-' . $category->parent ] = [];
			}
			$categories_by_parent[ 'cat-' . $category->parent ][] = $category;
		}

		$tree = $categories_by_parent['cat-0'];
		unset( $categories_by_parent['cat-0'] );

		foreach ( $tree as $category ) {
			if ( ! empty( $categories_by_parent[ 'cat-' . $category->term_id ] ) ) {
				$category->children = $this->fill_category_children( $categories_by_parent[ 'cat-' . $category->term_id ], $categories_by_parent );
			}
		}

		return $tree;
	}
```
I couldn’t find any mention of this in the forum. Would appreciate any tips for fixing. I’m not able to follow the code enough to understand what is wrong with this that is causing the warning. But the site appears to be functioning properly so perhaps this is something that I can ignore? I’m not using blocks.

Hi @burnstuff

The code seems fine! To help us diagnose it better, could you please share a copy of your site’s System Status?

You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”.?

Once you’ve done that, paste it here in your response.

All the best,

Plugin Support

Sorry, I’ve been away. Thank you for your reply and offer to assist. Not sure if this is related, but I also started seeing this error as well:\

Hello,

Thanks for sending this information. Is possible there is a conflict with the theme or any plugin?

You can switch your theme to Storefront temporarily, disable all plugins except for WooCommerce, and check the issue again.

After that make sure to enable plugins one by one until you find the origin/cause of the issue, to learn more please check How to do a conflict test.

Let us know if this makes a difference.
