Cms: UnknownPropertyException

[Christo55]

Description

When I click on a page to edit, I get:

Unknown Property – yii\base\UnknownPropertyException
Getting unknown property: craft\behaviors\ContentBehavior::categoriesMatrix

        throw new UnknownPropertyException('Getting unknown property: ' . get_class($this) . '::' . $name);

Steps to reproduce

1. Not sure, I tried to update craft and got an error with composer.json permissions, fixed the permissions and ran update again. It's still broken
   2.

Additional info

• Craft version: "craftcms/cms": "3.0.26.1",
• Supertable "verbb/super-table": "2.0.10",

Can you try deleting your storage/compiled_classes/ folder and see if that fixes it?

We have had the same issue happen — any chance that because we have Opcache running in production mode (i.e., holding ContentBehavior in memory), then it might not be seeing updates to the Behavior classes? Maybe those compiled classes need to have opcache_invalidate run on them (if it's not already) to pick up those changes?

In our case we added a field to a section, hit save, and it then failed out trying to re-save the entries in that section (across multiple sites) - here was the readout:

We already do call opcache_invalidate() when regenerating ContentBehavior.php and ElementQueryBehavior.php.

Just yesterday someone pointed out a race condition that could result in those classes missing some field handle properties (#3400). That could be the culprit here too, in which case it’s fixed for the next release.

That would make sense - thanks!

Going to close this for the time being, but let me know if it crops up again after updating to 3.0.29 when that comes out next week.

Worked for me too, for a similar issue.
I was getting the error Setting unknown property: craft\models\Update::packageName
