Dojo error in CMS edit mode on a specific page after CMS 12 upgrade.


Hello all,

We did an upgrade from CMS 11 to 12 and while the site is up and running, we have observed that for a couple of page types am not able to get to the CMS. There is error in DOJO and I tried debugging it and see following error.

epi.js:4092 TypeError: Cannot read properties of undefined (reading 'hasSubProperties')
    at Object.populateContentModel (ModelPopulation.js:25:38)
    at Object.<anonymous> (ContentViewModel.js:808:45)
    at dojo.js:3135:55
    at signalListener (dojo.js:8325:21)
    at signalWaiting (dojo.js:8316:4)
    at Deferred.resolve (dojo.js:8480:5)

On this page type I have a property ContentReference for HeroImage and in debugging this ModelPopulation.js I see that propertyMetadata for HeroImage is undefined and it errors out. Any inputs on what could I be missing and how to resolve this?

The error suggest that some property wasn't migrated properly. Have you checked so the content types don't have any dangling properties?

How does this look for the page types that are having issues? (Navigate to /EPiServer/EPiServer.Cms.UI.Admin/default#/ContentTypes)

Content type does have some dangling properties but the property (HeroImage) on which it is erroring out exists in code.

Found that there were some properties marked as JsonIgnore (along with HeroImage). On removing those attributes the issue got resolved and able to get into edit mode.

Still seem like a bug to me. Thanks for telling.

Sounds like this (now fixed) issue, I think? 

Fixed in: EPiServer.CMS.UI 12.22.7

Thank you for the update Daniel. I will try to upgrade and check it out by putting back the code.
