Illegal offset type in isset or empty" at ContentEntityBase.php  

There is not enough information to diagnose the problem, and automated tests would catch this if it happened in a basic install of Drupal.

If you have a full stack trace, that might be helpful. And if you can reproduce this starting from a fresh install of Drupal, please write down the steps required to create the error.

This got resolved it was a error driving from a custom module code.

I added the patch but receive the following error when the module is enabled, it goes away once the module is disabled:
