Article Schema error (mainEntityOfPage)

Hello,

Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.

We were able to reproduce the error and have logged it. Please allow us some time to test and release a fix. For now, to fix the issue on your site, please add following filter code in your theme’s functions.php file:

add_filter( 'rank_math/json_ld', function( $data, $jsonld ) {
	if ( isset( $data['richSnippet'] ) && ! isset( $data['richSnippet']['isPrimary'] ) ) {
		$data['richSnippet']['isPrimary'] = true;
	}

	if ( ! empty( $data['publisher'] ) && 'Organization' !== $data['publisher']['@type'] ) {
		$data['publisher']['@type'] = [
			'Organization',
			$data['publisher']['@type']
		];

		if ( ! empty( $data['publisher']['image'] ) ) {
			$data['publisher']['logo'] = is_array( $data['publisher']['image'] ) ? $data['publisher']['image'] : [
				'@type' => 'ImageObject',
				'url'   => $data['publisher']['image'],
			];
		}
	}

	return $data;
}, 99, 2);

I hope that helps. Thank you.
