Error 709 : ContentId is not valid for the specified landing page content
Hi,
I am trying to update a rich text content section of a Landing page with element like - <div id="heading" mktoName="Heading" class=" col-55 mktoText "> by REST API.
It throws 709: business rule violation.
If a change the css class to class=" mktoText " then the POST operation works. col-55 is a custom class created by the user, which can't be ignored.
How can I fix this error?
