Valet + macOS + PHP 7.1: errors and Laravel exceptions don't work anymore

So I upgraded my local PHP but errors and Laravel exceptions don't work anymore. php.ini is development oriented (errors are displayed) and the .env file didn't change. Does anyone experienced this issue?

php.ini file (I verified its path with php -i command:

error_reporting = E_ALL
display_errors = On
display_startup_errors = On
log_errors = On
html_errors = On

.envfile:

APP_ENV=local
APP_DEBUG=true
APP_LOG_LEVEL=debug
