500 error on register with postHooks

Hello!
I have 500 error with Register snippet when I use the postHook option. It happens because $this->user is empty but function try to get the user object parameter.
I've added checking the user value before geting parameters in row 412 of the processor if ($this->user == null)
Hope it help.

When a post-hook snippet is executed, references to $this->user and $this->profile are added to the snippet properties.

Login/core/components/login/processors/register.php

Lines 355 to 356 in bcb5ec2

    
           $fields['register.user'] =& $this->user; 
        
           $fields['register.profile'] =& $this->profile;

Login/core/components/login/model/login/loginhooks.class.php

Lines 117 to 119 in bcb5ec2

    
           $properties['fields'] =& $this->fields; 
        
           $properties['errors'] =& $this->errors; 
        
           $success = $snippet->process($properties);

Before $snippet->process() is called $this->user is of type MODX\Revolution\mysql\modUser and $this->profile of type MODX\Revolution\mysql\modUserProfile.
After $snippet->process() they are both arrays. Why?

	$fields['register.user'] =& $this->user;
	$fields['register.profile'] =& $this->profile;

	$properties['fields'] =& $this->fields;
	$properties['errors'] =& $this->errors;
	$success = $snippet->process($properties);
