Translate custom error in Exception

[VladZP]

Hi there! I wrote hook which check not empty field when manager change status in account entity.
I added transated labels in my Global.json my language (uk_UA)

{
"errorMessages": {
"ErrorField1Empty": "Перехід на статус 2 наможливий, поле field1 не може бути порожнє.",
"ErrorField2Empty": "Перехід на статус 3 наможливий: поле field2 не може бути порожнє."
}
}​ 

My function which check field:

protected $language;

public function __construct(Language $language)
{
$this->language = $language;
}

public function beforeSave(Entity $entity, array $options = [])
{
$status = $entity->get('status');
$prevStatus = $entity->getFetched('status');

if ($status === 'test1' && $prevStatus !== 'test1') {
$field1 = $entity->get('field1');
if (empty($field1)) {
$message = $this->language->translate('ErrorField1Empty', 'errorMessages');
throw new \Exception($message);
}
}

if ($status === 'test2' && $prevStatus !== 'test2') {
$field2 = $entity->get('field2');
if (empty($field2)) {
$message = $this->language->translate('ErrorField2Empty', 'errorMessages');
throw new \Exception($message);
}
}
}​ 

It construction works, $message got value from errorMessages, but it can't show me error on Ukrainian Language.
Any ideas? Is It possible?
Best wishes!

Use throw \Espo\Core\Exception\Error::createWithBody https://github.com/espocrm/espocrm/b.../Error.php#L49

        \Espo\Core\Exceptions\Error::createWithBody(
            'some-reason',
            \Espo\Core\Exceptions\Error\Body::create()
                ->withMessageTranslation('someTranslationKey', null, [
                    'placeholder' => 'value',
                ])
                ->encode()
        );​ 

Translation path in a language file: messages > someTranslationKey.

This exception will be translated in the front-end.

{placeholder} will be replaced with 'value'.
