[BUG]: Fatal error: Return value of Phalcon\Mvc\View\Engine\AbstractEngine::partial() must be of the type string, null returned in Unknown on line 0 Call Stack

cphalcon-4.0.0-rc.1

<?php $this->partial('_partials/header'); ?>
<?php echo $this->getContent(); ?>
<?php $this->partial('_partials/footer'); ?>

Why you call second partial from view?

Instead

<?php $this->view->partial('_partials/footer'); ?>

Try

<?php $this->partial('_partials/footer'); ?>

i use

<?php $this->view->partial('_partials/header'); ?>
<?php echo $this->getContent(); ?>
<?php $this->view->partial('_partials/footer'); ?>

is ok

<?php $this->partial('_partials/header'); ?>
<?php echo $this->getContent(); ?>
<?php $this->partial('_partials/footer'); ?>

works fine on v3.4.4, but v4.0.0-rc.1 will ouput Fatal error

I need to confirm this but it seems that we will need to add null to the return type for partial

This is not an issue with v3 because it uses an older version of Zephir that allows this to pass, whereas v4 is more strict with interfaces and return types.
