    Good day,

    On PHP 8.1.23, Yoast 21.2, WordPress 6.3.1, with WP_DEBUG enabled, using the default Twenty Twenty-Three theme, I am receiving the following stack trace on certain pages. The deprecation notice prints twice when it occurs – once relating to open_graph_description, and once relating to twitter_description. If it helps, this is the associated page in our production environment (which uses a different theme, but the deprecation notice is independent of the theme): https://www.jwcc.edu/career-services/career-cruising/

    It definitely appears as if the deprecation warning is because Yoast is passing along something null at some point, but I’m not sure exactly where it’s occurring. Please let me know what additional details I can provide to assist in debugging.

    Hello @leonardcraft

    Thanks for reaching out about the notices. First, deprecations are NOT errors and should NOT be treated as such.
    Until PHP 9.0, everything which is deprecated will still work as it did before. The deprecation is visible because WP_DEBUG is enabled and not in the WordPress admin panel.

    Deprecations don’t break any WordPress functionality and are not actual errors, so you can ignore them. And not to worry, the reason that causes that deprecation will be fixed eventually.

    Right, I understand that this is just a deprecation notice (pardon the URL – I corrected the title in an edit after posting). I’m sharing this so your team is aware. If I can provide any additional details to help in the debugging process, let me know. If this is a known bug, apologies for submitting a duplicate support topic.

    Kind regards,

    Leonard
