What happened?

My installation is using docker compose.
I was using mautic/mautic:5-apache which was working well, and just updated the tag to mautic/mautic:5.1.1-apache.
The containers start up fine, but on opening the web page it shows:

Warning: require(/var/www/html/vendor/composer/../../docroot/app/AppTestKernel.php): Failed to open stream: No such file or directory in /var/www/html/vendor/composer/autoload_real.php on line 41

Fatal error: Uncaught Error: Failed opening required '/var/www/html/vendor/composer/../../docroot/app/AppTestKernel.php' (include_path='.:/usr/local/lib/php') in /var/www/html/vendor/composer/autoload_real.php:41 Stack trace: #0 /var/www/html/vendor/composer/autoload_real.php(45): {closure}('7f9097acd45f80f...', '/var/www/html/v...') mautic/mautic#1 /var/www/html/vendor/autoload.php(25): ComposerAutoloaderInitbccd3ad3db7b670fdd12e172f6f4c035::getLoader() mautic/mautic#2 /var/www/html/docroot/autoload.php(13): require('/var/www/html/v...') mautic/mautic#3 /var/www/html/docroot/app/config/bootstrap.php(5): require('/var/www/html/d...') mautic/mautic#4 /var/www/html/docroot/index.php(9): require('/var/www/html/d...') mautic/mautic#5 {main} thrown in /var/www/html/vendor/composer/autoload_real.php on line 41

I also tried updating to mautic/mautic:5.1.0-apache, and it gives the same error.

How can we reproduce this issue?

Step 1: Clone the mautic/docker-mautic repo, edit the docker-compose.yml file to set the apache version mautic/mautic:5-apache and run docker compose up -d to install mautic. Check the website to see that it's working fine.
Step 2: Edit the docker-compose.yml to change the version to mautic/mautic:5.1.1-apache in the three containers.
Step 3: Run docker compose down && docker compose up -d to rebuild the containers. Go to the website, and it shows the error above.
