After installing the skeleton per the instructions in the README and running COMPOSER_PROCESS_TIMEOUT=0 composer run and visit http://localhost:8888 or http://localhost:8888/index_dev.php I get the following error in a JS alert:
An error occurred while loading the web debug toolbar (500: Internal Server Error).
Do you want to open the profiler?
That error pops up every time I click "OK". When I hit "Cancel" I see the following:
RuntimeException in ArgumentResolver.php line 82: Controller "Symfony\Bundle\WebProfilerBundle\Controller\ProfilerController::panelAction()" requires that you provide a value for the "$request" argument (because there is no default value or because there is a non optional argument after this one).
