TypeError: ze.models.Page is not a constructor

Hi,

I’ve seen this issue raised before (and here) but it doesn’t seem to have an obvious resolution. So I thought i’d give all the info I have to try and get this resolved;

Here is the full error from the block editor:

TypeError: ze.models.Page is not a constructor

Site info:

PHP: 8.2 – though not really relevant as a JS issue, but also happens on other versions
Theme: Twenty Nineteen – also any other theme I have tested
Plugins Active: Yoast 24.0
Browsers: Chrome, Safari Firefox – all latest at the time of writing
Core: 6.7.1

Also tested using troubleshooting mode in health check with the issue still present – similarly on local and production environments.

Steps to reproduce

• Create a hierarchical post like a page or any custom post type that allows a parent/child relationship
• Assign a page parent to the new page
• Publish
• Head to All pages
• Edit a different page
• Go back to all pages
• Edit the new page that has a parent

The last 4 steps aren’t happening every time with a brand new page for me, but anything older then it is – but clearing site data/using a private browser does seem to trigger the error every time

You should get the following popup:

View post on imgur.com

Looking in the source, I can see this call ze.loadPromise.done((()=>{new ze.models.Page({id:n}).fetch().then… but as the javascript has been obfuscated, I can’t give much more insight

Hope this can get resolved

Thanks
Phil
