Where did I go wrong in the php version?

Question

PHP

I'm trying to run a project wrapped in docker, but the following arrives in the logs to the php-worker container:

Parse error: syntax error, unexpected '|', expecting variable (T_VARIABLE) in /app/vendor/symfony/console/Input/ArgvInput.php on line 304

. And when I try to connect through a browser, it displays This site can’t provide a secure connection(port 443) and 404 page not found(port 80) I use the 8th version of php and the 9th version of Laravel. What could be wrong?

Answer 1

404 shows because the .env file says:
APP_DEBUG=false
Set it to true and the error information will be displayed on the screen.
