Call to a member function deleteDescendants() on null

[earthwytch]

Has anyone seen the above error when attempting to delete page entries in the control panel?

This is only a problem in production, which is deployed as an Azure App Service container. In my local development environment I can delete without any issues.

Any suggestions as to where I can start looking? Thank you 🌞

Here is the entire trace:

Hey 👋

There seems to be an existing bug report open for this error: #5490

[earthwytch]

Ah ok, I dismissed that because it appeared multisite specific. Is there any progress on fixing it? The only way we can delete pages is to ssh into the server and manually delete the entry yaml file and then clear the cache to rebuild the tree which is proving to be a bit frustrating for the team 🙂

I don't believe we've started working on it yet. You can subscribe to the issue to be notified of any progress.
