Laravel App Platform Cron Job

Hello, i’ve been trying to run a cron job with a worker component.

This is my code:

while true; do echo “=> Running scheduler” cd core && php artisan booking:sync || true; echo “=> Sleeping for 300 seconds” sleep 300; done

My artisan is inside a folder called core, the first time it works, but the second time i get an error of course because it’s already inside core folder. Is there a way to execute the cd core only once?
