Hi,

Can you check core embed component if you are using it?

That component required policy to set for the template.

Do you have any sling model for max-button component? Could you please brief us about htl/sightly part of max-button component.

Ronnie09 · 5/5/22

Yes we have sling model for max-button.
Max-button have design dialog - With allowed embeddedable.

Max-button have embeddable node- youtube, wimeo and more

Sightly code have links url, label, button type, embeddeables

DEBAL_DAS · 5/5/22

From the error statement it looks like due to absence of embeddedable node you are getting null pointer exception for the first time.

Are you reading embeddedable as object in sling model? If yes, have you done null check.

From the logs, I think the problem is with the template policy.

I think the component you are trying to include is not allowed within the template policies. Try adding that component to the list of allowed components for the template.
