The weird part is that toHtml method should return a string. Do you know why it returns null in your case?

@vovayatsyuk @0m3r men you're fast.

Do you know why it returns null in your case?

No, I don't recognize the cause. Here is the full strack trace. Maybe a 3rd party thing. Errors appear on category and product pages.

1 exception(s):
Exception #0 (Exception): Deprecated Functionality: trim(): Passing null to parameter #1 ($string) of type string is deprecated in /var/www/html/vendor/swissup/module-core/Plugin/SetEmptyStringIfOutputEmpty.php on line 18
