Warning in Chrome browser while monitoring the end user performance

I am working on a project for monitoring the end user performance of an application. Functionality wise everything is working fine, but in chrome browser when I am checking the console option in the dev tools I am getting a warning message. The message says as mentioned below -


(index):17 A Parser-blocking, cross site (i.e. different eTLD+1) script,, is invoked via document.write. The network request for this script MAY be blocked by the browser in this or a future page load due to poor network connectivity. If blocked in this page load, it will be confirmed in a subsequent console message.See for more details.
(anonymous) @ (index):17


After an initial research I could find that its happening only in Chrome because of Cross site Synchronous Java script getting called through document.write. Is there a way to remove this warning?

Hi, I think this article might have a way to workaround that error:


@Gaurav.Soni please confirm. Also, the error message is formatted strangely, probably want to fix that. Thanks.

Encountered the same issue as OP. The suggested workaround worked for me.
