We are receiving a cross origin access error while embeding domo as an iframe into our portal. As a work around If we disable the xframe options check then it is working as expected How can we fix this ?
Because your website and domo are coming from different domains by default you'll get the CORS error which is a standard security check to make sure you're not attempting to access a website from a completely different website. This is to avoid click-jacking attacks.
There isn't a way to avoid this except for turning off the xframe options like you're doing.
