Is it possible to include embed component in html?

[danielchido]

I'm trying to add embed component by html by using this tag:

<sly data-sly-resource="${'embed' @resourceType='/apps/site/components/embed'}" />

But when I try to edit the dialog I get this error:

com.adobe.cq.wcm.core.components.internal.servlets.embed.EmbeddableOptionsDataSourceServlet

Exception:

If I add the same component manually it works perfectly.

Hi @danielchido ,

The issue could be with missing node for embed component in the content , that you need to create your component for embed using cq:template node under main component you are trying to add.

Tried embedding with cq:template to helloworld component and it works as expected!
