Identifier com.adobe.cq.inbox.ui.DateFormatter cannot be correctly instantiated by the Use API

[kiriku007]

Hi everyone,
I'm new AEM user and i can not solve this.

In TouchUI when I click on the Inbox (the bell icon /right upper corner) and on that context menu on "View All()" then I just see a server error message.

Identifier com.adobe.cq.inbox.ui.DateFormatter cannot be correctly instantiated by the Use API

Cannot serve request to /aem/inbox in /apps/cq/inbox/gui/components/inbox/inboxitem/list/list.html

Exception:

Hi @kiriku007 ,

I believe you have recently upgraded AEM project. Please test this code on a fresh AEM install and see if it throws the same error. This will tell us if the issue is with the code or upgraded AEM version.

Check some properties have null in the CRX/DE for any node.

Additionally, try using @Optional annotation while trying to inject fields using Sling Models. The reason -

When you are using Sling Models for injecting fields and you try to drag and drop the component for the first time, the model will check for the all the injected values. Since you are dropping the component for the first time and there are no values stored for it in the JCR and as result the error will be thrown. But when we use the @Optional annotation the injection strategy will be considered as optional for the field and hence it won't check for the values.

Reference: https://sling.apache.org/documentation/bundles/models.html

Hope that helps!

Regards,

Santosh
