Remote SPA - not able to access 'SPA' tab to set remote URL


Level 1

Hi, I've been trying to set up remote SPA by following instructions here . I've done everything mentioned in the document but when I open up 'WKND App Home Page' page properties to set up remote URL (as mentioned here); the SPA tab doesn't open at all. 

AEM Version in use: on-prem 6.5.17



This is the error I see while opening properties:



Any help will be appreciated!

It looks like something is wrong set in your page, can you please check:

- The resourceType is pointing to an existing resource

- The wknd SPA project (AEM side) is successfully installed

- Check if other tabs from other projects are rendering ok.

Then try to re-install the wknd SPA project, and/or bounce the instance once.

Thank you Esteban. I went back and kept looking into different things as you suggested. Turns out issue has nothing to do with SPA project. For some reason User principal is is null (in com.adobe.cq.sites.ui.models.admin.security.permission.UserAllowedActions) thus causing null pointer exception.


Not sure how user principal is coming as null or why there is no null check.
