CakePHP: upgrade from 3.6.x to 4.0 "Missing Template Exception"

Question

I followed the upgrade guide (after I upgraded from 3.6 to 3.8) but I get this error:

Error: [Cake\View\Exception\MissingTemplateException] Template file "Error\error500.ctp" is missing

....

If you want to customize this error message, create src\Template\Error\fatal_error.ctp

After the upgrade procedure my templates moved to app_name\templates directory and renamed to *.php instead of *.ctp . I updated the app.php and app.default.php with the new paths:

'App' => [
        'namespace' => 'App',
        'encoding' => env('APP_ENCODING', 'UTF-8'),
        'defaultLocale' => env('APP_DEFAULT_LOCALE', 'en_US'),
        'defaultTimezone' => env('APP_DEFAULT_TIMEZONE', 'UTC'),
        'base' => false,
        'dir' => 'src',
        'webroot' => 'webroot',
        'wwwRoot' => WWW_ROOT,
        //'baseUrl' => env('SCRIPT_NAME'),
        'fullBaseUrl' => false,
        'imageBaseUrl' => 'img/',
        'cssBaseUrl' => 'css/',
        'jsBaseUrl' => 'js/',
        'paths' => [
            'plugins' => [ROOT . DS . 'plugins' . DS],
            'templates' => [ROOT . DS . 'templates' . DS],
            'locales' => [ROOT . DS  . 'Locale' . DS],
        ],
    ],

But still the application is looking for the template files with .ctp extension and under src\Template\...

What am I missing?

From my experience:

Upgrade CakePHP 3.x to 4.x

composer update
run phpstan from --level 0 to 2 and fix your code or test in scrutinizer
read 4.0 Migration Guide : https://book.cakephp.org/4/en/appendices/4-0-migration-guide.html
read 4.0 Upgrade Guide : https://book.cakephp.org/4/en/appendices/4-0-upgrade-guide.html Steps:
Install the upgrade tool
Rename locale files
Rename template files
Once you've renamed your template and locale files, make sure you update App.paths.locales and App.paths.templates paths to be correct.
From your app composer file remove all cakephp/* (cakephp3) packages, also phpstan, code standards, phpunit,.. run composer update
Applying Rector Refactorings
composer require --update-with-dependencies "phpunit/phpunit:^8.0"
composer require --update-with-dependencies "cakephp/cakephp:4.0.*"
Install fresh cakephp4 inside your app folder. Example: mkdir cakephp4 && cd cakeph4; and run composer create-project --prefer-dist cakephp/app:4.* .;
compare your old cakephp files with files from cakephp4 folder, update all and copy missing files
delete cakephp4 and upgrade folders
don't forget at top of you php files to add <?php declare(strict_types=1);
composer cs-check then composer cs-fix

Hi there, thanks for sharing your way to go. I just followed your way and saw, that the order of the steps "remove all cakephp3-packages" and "apply rector refactorings" must be switched. After removing cakephp-packes, rector can't apply changes due to missing classes. Despite of that, very nice. Can you shortly give an explanation or command, how to do step 2? – MikeRoss Apr 16 '20 at 10:22
@MikeRoss step 2: Rename locale files ?? Or? – Salines Apr 16 '20 at 11:15
I meant step "run phpstan from --level 0 to 2 and fix your code or test in scrutinizer" could include a short explanation of how to run this command (e.g. for me, I didn't use phpstan before). Some that might read your instructions (that worked pretty good, btw) may be thankful. – MikeRoss Apr 16 '20 at 12:54
@MikeRoss ```composer require --dev phpstan/phpstan``` then in console run ```./vendor/bin/phpstan analyse src plugins --level 0``` this command output some basic errors, with level 1 you have deeper outputs, etc. Try to find and fix error and Deprecations warnings. For example $this->request->.. emit Deprecated warning .. – Salines Apr 16 '20 at 13:18
"After removing cakephp-packes, rector can't apply changes due to missing classes." remove from composer file, not from vendor folder – Salines Apr 16 '20 at 13:20

Thanks for the command. Will try this with my second project. Regarding your last comment ("remove from composer file, not from vendor folder"): I removed from composer.json and then - just like you told in this step, ran composer update. Maybe, I deleted too many packages ;) – MikeRoss Apr 16 '20 at 13:24
