Unable to overlay /libs/core/wcm/components/form in AEM Cloud SDK

[_CL]

Hey guys,

I was trying to overlay form components from /libs/core/wcm/components/form to /apps with "Match Node Types" enabled.

I am getting the below errors in the logs -

Any help on this?

Hi,

Unfortunately, I’ve seen this behavior as well, and in my humble opinion, it is expected because, on Cloud— which is what the SDK is trying to mimic— you are not allowed to perform such operations. You have two options: either create the overlay manually or create the overlay in an AEM on-premise instance, package it, and install it back into your AEM SDK instance.

I can confirm what @EstebanBustamante said. Interestingly, overlay doesn't work but you can still copy-paste stuff from /libs to /apps, delete what you don't need, and extract it with a package to your codebase.

Good luck,

Daniel
