Undefined array keys

Hi @magazine3,

just to clarify: your recent link to the github issue points to another error while enabling the plugin connected to schema_type.php.

The post’s author is referencing a PHP warning from php8+ affecting output/function.php (captured also from my PHP logs as follows):

PHP Warning:  Undefined array key "title" in .../schema-and-structured-data-for-wp/output/function.php on line 3408
PHP Warning:  Undefined array key "description" in .../schema-and-structured-data-for-wp/output/function.php on line 3410
PHP Warning:  Undefined array key "uploadDate" in .../schema-and-structured-data-for-wp/output/function.php on line 3411
PHP Warning:  Undefined array key "duration" in .../schema-and-structured-data-for-wp/output/function.php on line 3412
PHP Warning:  Undefined array key "viewCount" in .../schema-and-structured-data-for-wp/output/function.php on line 3418

I do not know why some of the array values remain empty, but as a quick fix, I just added a default value.

Same problem here on PHP 8.1. Hope this will be fixed asap. Thanks
