I have added an iframe in the dashboard -
<iframe src="https://saurabh.mindtickle.com" frameborder="0" referrerpolicy="no-referrer"></iframe>
I am getting an error - DashboardIframeEmbed.js:40 Failed to execute ‘postMessage’ on ‘DOMWindow’: The target origin provided (‘https://preview.hubspoteditor.com’) does not match the recipient window’s origin (‘https://app.hubspot.com’)
The origin policy contains *.hubspot.com still I got an error. Whats the issue and how can it resolved?
Hi @gangwalsaurabh 
It’s my opinion this is likely something you’ll have to pick up with Mindtickle support. In the meantime, you might consider reviewing the HubSpot Knowledge Base article, “Embed external content on a dashboard” (you’re likely already aware of it, but thought I’d share just in case).
On a side note, is the Mindtickle content you’re trying to embed into your HubSpot dashboard intended to be accessed via an iframe? The reason I ask is that if I try to access your iframe’s source URL, I am redirected to a login screen.
I hope that proves helpful. Please let me know if you have any follow-up questions.
