Hooks error

[DevMostafa]

tanya I've added a new hook file which always gives me a PHP error:

[Wed Feb 07 13:15:26.288032 2018] [:error] [pid 64097] [client 10.20.16.71:55948] PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 20480 bytes) in /var/www/espo/application/Espo/ORM/DB/Query/Base.php on line 414

I've attached the Hook file and I want to know if there's a trigger make the Hook dynamic without save the entity.

Hello Tanya,
I made it and have this error in the log file:

[2018-02-07 13:20:50] Espo.ERROR: Uncaught Exception TypeError: "Argument 1 passed to Espo\ORM\DB\Mapper::select() must be an instance of Espo\ORM\IEntity, null given, called in /var/www/espo/application/Espo/ORM/Repositories/RDB.php on line 187" at /var/www/espo/application/Espo/ORM/DB/Mapper.php line 103 {"exception":"[object] (TypeError(code: 0): Argument 1 passed to Espo\\ORM\\DB\\Mapper::select() must be an instance of Espo\\ORM\\IEntity, null given, called in /var/www/espo/application/Espo/ORM/Repositories/RDB.php on line 187 at /var/www/espo/application/Espo/ORM/DB/Mapper.php:103)"} []

Somewhere you want to load entity, which not exists. Check all getEntity and getRepository.

Now it didn't give errors, but saving took many time and didn't return yet.
