Hi,

I am integrating AEM Adaptive form on existing AEM as a cloud site.

I have created two adaptive form for testing purpose in local aem instance without existing site code

Adaptive form with Foundation component
Adaptive form with core components

and both are working as expected but after deploying the site code its start breaking in author mode and on browser console I see below error.

After some investigation I found that one the component have clientlib folder and it have dependencies as: cq.authoring.editor.sites.page and If I remove this dependency form is working as expected.
