Laravel Optimization Commands

When I add the code with USER root it deployed successfully without getting any errors.

USER app
RUN php artisan config:cache \
    && php artisan route:cache \
    && php artisan view:cache
USER root

But when I open the site fly open, the Laravel app responds with a 500 SERVER ERROR

If a remove the code from the Dockerfile the Laravel app works fine without the 500 SERVER ERROR.

Can you help? Thank you very much.
