Hi Experts!

I am getting the following errors after upgrading php version from 7.2 to 7.3.

[**Warning** (2)](javascript:void(0);): count(): Parameter must be an array or an object that implements Countable [**CORE\src\Database\QueryCompiler.php** , line **128**]

I am using cakephp 3.3.8.

Thanks in advance!
