Warning error in class-author.php on line 41

Hello Rank Math Support,

I’m using WordPress 7 and Rank Math SEO (free) v1.0.271.1. On the front-end, I’m seeing this PHP warning:

Warning: Undefined array key "url" in
/home/gameblad/public_html/wp-content/plugins/seo-by-rank-math/includes/modules/schema/snippets/class-author.php on line 41

It looks like in RankMath\Schema\Author::process() the plugin accesses:

$jsonld->parts['url']

but in some requests the url key is not set in $jsonld->parts, so PHP 8+ triggers Undefined array key “url”.

Expected behavior: no warnings should be output on the site.
Suggestion: add an isset() / null-coalescing check and use a fallback URL when parts['url'] is missing (e.g. $data['WebPage']['@id'] or home_url('/')), before appending #author.

Please let me know if you need any more details (page type where it happens, PHP version, debug log, etc.).
Thank you.
