Failed to execute 'postMessage' on 'DOMWindow'

mohammedniyas — Mon, 06 Nov 2017 07:28:03 GMT

I'm trying to create a custom visual. I'm getting following errors in the console while starting the project.

Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://app.powerbi.com') does not match the recipient window's origin ('null').

Can anyone help me to understand this issue here?

Hello @mohammedniyas

Power BI create a special isolation that protects the main window against custom visuals.

The isolation is implemented by using sandbox mode of iframe and cloning the windows object.

Could you please clarify the reason of using postMessage?
