PHP Notice: Trying to get property ‘canonical’ of non-object
-
In our debug.log, we’re getting a lot of the PHP notices below. Is this normal and is there a way to resolve them (or for your team to resolve them in a future update)?
PHP Notice: Trying to get property 'canonical' of non-object in .../wp-content/plugins/wordpress-seo/src/integrations/front-end/feed-improvements.php on line 160

Hello @hastibe
Thanks for sharing the error with us. It would be helpful if you could let us know how to reproduce the error. Do you by chance know what triggered the error?
Unfortunately, I am not sure what specifically is triggering the error, as the entry is showing-up several hundred times each day in the debug.log — maybe certain page views by users?
We would like to continue to investigate this issue and therefore, we expect few more information about your setup. This might help us replicate the issue on our end:
1. Can you confirm you are using the most recent Yoast SEO, v20.8? If you update, does the issue resolve?
2. Are all your non-Yoast plugins and themes also updated?
3. Can you confirm you are using WordPress 6.2? Please know that if you are using an older version of WordPress Core you may experience unexpected behavior with Yoast. This guide explains more: https://yoast.com/why-we-dont-support-old-wordpress-versions/.
4. Have you performed SEO Data Optimization (SEO > Tools)? Does this help to prevent errors?
We look forward to hearing from you.
This thread was marked resolved due to a lack of activity, but you’re always welcome to re-open the topic. Please read this post before opening a new request.
Yikes, it has only been like 72 hours since the last post!
We can confirm #1-3. We have performed #4 and are monitoring whether it has resolved the errors, and will post back with an update.
@suascat_wp — to follow-up on my previous post: running SEO Data Optimization did not help prevent the issue, unfortunately:
