Magento – Call to a member function getId() on null in /var/www/vhosts///vendor/magento/framework/View/Model/Layout/Merge.php

magento2PHPtheme

This error appears when I try to go to the frontend of the Server web. The admin works perfectly.

And even further, if I use the local files and the local installation of Magento everything works fine.

I'm getting a HTTP error 500, and in the logs appears this code:

Got error 'PHP message: PHP Fatal error: Uncaught Error: Call to a member function getId() on null in /var/www/vhosts/a//vendor/magento/framework/View/Model/Layout/Merge.php:751\nStack trace:\n#0
/var/www/vhosts///vendor/magento/framework/View/Model/Layout/Merge.php(684): Magento\Framework\View\Model\Layout\Merge->_getPhysicalTheme(Object(Magento\Theme\Model\Theme))\n#1
/var/www/vhosts///vendor/magento/framework/View/Model/Layout/Merge.php(633): Magento\Framework\View\Model\Layout\Merge->_loadFileLayoutUpdatesXml()\n#2 /var/www/vhosts//vendor/magento/framework/View/Model/Layout/Merge.php(527): Magento\Framework\View\Model\Layout\Merge->getFileLayoutUpdatesXml()\n#3 /var/www/vhosts///vendor/magento/framework/View/Model/Layout/Merge.php(506): Magento\Framework\View\Model\Layout\Merge->_fetchPackageLayoutUpdates('default')\n#4 /var/www/vhosts///vendor/magento/frame…\n'

The code that fails is this one:

protected function _getPhysicalTheme(\Magento\Framework\View\Design\ThemeInterface $theme)
{
    $result = $theme;
    while ($result->getId() && !$result->isPhysical()) {
        $result = $result->getParentTheme();
    }
    if (!$result) {
        throw new \Magento\Framework\Exception\LocalizedException(
            new \Magento\Framework\Phrase(
                'Unable to find a physical ancestor for a theme \'%1\'.',
                [$theme->getThemeTitle()]
            )
        );
    }
    return $result;
}

I run the commands:

rm -rf pub/static/*;
/opt/plesk/php/7.0/bin/php bin/magento setup:upgrade; 
/opt/plesk/php/7.0/bin/php bin/magento setup:static-content:deploy; 
/opt/plesk/php/7.0/bin/php bin/magento setup:static-content:deploy es_ES;

While I was writing the question I managed to get it fixed:

I have modified my theme in app\design\frontend\TemplateMonster\theme094\theme.xml:

<theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Config/etc/theme.xsd">
<title>TemplateMonster Theme</title>
<parent>Magento/blank</parent> <!--Added-->
<media>
    <preview_image>media/preview.jpg</preview_image>
</media>

The <parent> tag was empty. Hope it helps someone.

Magento – Fatal error: Uncaught Error: Class ‘Cli’ not found

This error has nothing to do with Plesk it's from the Magento script itself. Whoever wrote it clearly has no idea of PHP OOP. Sorry but it's true.

There's nowhere to be found an "use" keyword in the script but you can clearly see that he's trying to use

Cli

class without specifying the namespace. That's the whole error if you change it to

  Magento\Framework\Console\Cli

it will work.

Change the bin/magento shell file from:

#!/usr/bin/env php
<?php
/**
 * Copyright © 2013-2017 Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */

if (PHP_SAPI !== 'cli') {
    echo 'bin/magento must be run as a CLI application';
    exit(1);
}

try {
    require __DIR__ . '/../app/bootstrap.php';
} catch (\Exception $e) {
    echo 'Autoload error: ' . $e->getMessage();
    exit(1);
}
try {
    $handler = new \Magento\Framework\App\ErrorHandler();
    set_error_handler([$handler, 'handler']);
    $application = new Magento\Framework\Console\Cli('Magento CLI');
    $application->run();
} catch (\Exception $e) {
    while ($e) {
        echo $e->getMessage();
        echo $e->getTraceAsString();
        echo "\n\n";
        $e = $e->getPrevious();
    }
    exit(Cli::RETURN_FAILURE);
}

#!/usr/bin/env php
<?php
/**
 * Copyright © 2013-2017 Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */

if (PHP_SAPI !== 'cli') {
    echo 'bin/magento must be run as a CLI application';
    exit(1);
}

try {
    require __DIR__ . '/../app/bootstrap.php';
} catch (\Exception $e) {
    echo 'Autoload error: ' . $e->getMessage();
    exit(1);
}
try {
    $handler = new \Magento\Framework\App\ErrorHandler();
    set_error_handler([$handler, 'handler']);
    $application = new Magento\Framework\Console\Cli('Magento CLI');
    $application->run();
} catch (\Exception $e) {
    while ($e) {
        echo $e->getMessage();
        echo $e->getTraceAsString();
        echo "\n\n";
        $e = $e->getPrevious();
    }
    exit(\Magento\Framework\Console\Cli::RETURN_FAILURE);
}

Take a look at the exit at the end...

Sorry if I offended somebody ;]
