Issue debug message after update to 5.0.3

[futur3int]

Just updated wp to 5.0.3 and got the following error (debug mode) appearing in the add plugin page from backoffice-> Notice: Undefined property: stdClass::$plugin in /../wp-includes/class-wp-list-util.php on line 150

Seems nothing is impacted by this issue but still i don’t know how to fix it (remove the message).

Is there a fix planed for next wp update?

Any clue?

Hi, just installed the classic editor back and it seems the issue is no more. So it as to be related to the new gutenberg editor.

Thank you for the bug report, @futur3int!

This notice is caused by the plugin update information cache having incorrect data in it, installing the classic editor plugin will have cleared that cache. Do you still see the problem if you deactivate and remove the classic editor plugin?

The most likely cause of the incorrect data getting into the cache is a paid version of a plugin that updates from a site other than WordPress.org.

See #44582 for more information.

Hi,

I desactivated and also removed the classic editor. The message was gone until today. Meanwhile I reeinstalled the classic editor and activated it. Now whatever im doing the message remains. Any clue? TY

I managed a fresh install 5.0.3 and installed my website back. Now the message is gone.
