I just upgraded my PM 3.2.1 to PM 3.5.7. But after the upgrade I noticed that sql property of textboxes is not working in some Dynaforms. It was working fine in 3.2.1. Also some cases are getting properly assigned to the next user. The case just disappears but can find the case in participated as it is in your inbox. But it is not in the inbox. In this case we are getting an error in __ERROR__ variable. Please see the error below.
The "Symfony\Component\Debug\Exception\FatalErrorException" class is deprecated since Symfony 4.4, use "Symfony\Component\ErrorHandler\Error\FatalError" instead.
MYSQL Version 5.7
PHP Version 7.3
