Error "Cannot set property 'eventManager' of null" in Dynamics 365

I got this script error popup when I opened record today. I have never got this error before and there's no change after I last opened the record days ago.

The error message is "TypeError: Unable to set property 'eventManager' of undefined or null reference".

I have no idea about it and need help to solve this issue. It occurred in both sandbox and prod environment.

Microsoft is removing their support for customised Javascript on forms. Please check if your Legacy form rendering is switched on . If yes , then switch it off and convert all your custom JS code to Xrmtoolkit compatible code.

Regarding your issue, there is a work around where you can wrap the addOnLoad call inside a window.setTimeout call with a delay of 1000ms.

window.setTimeout(onload(){//your code}, 1000);

I also have this problem. It seems that last crm system update contains some changes regarding js. In my case this error is made by the js function where I add OnLoad event to subgrid. If that function is disabled everything works fine.
