Troubleshooting Bref Docker Deployment with Octane Handler

[pra-cloud]

I want to deploy my code on Docker over Lambda. I obtained this file from the documentation regarding PHP-FPM, but I want to use Octane as a handler. I have made some changes in my Dockerfile, replacing the public/index.php with the Octane handler. After deploying to Lambda, I am encountering this error:

1. working dockerfile :-

FROM bref/php-81-fpm:2

COPY --from=bref/extra-redis-php-81:1 /opt /opt
COPY --from=bref/extra-gmp-php-81:1 /opt /opt

COPY . /var/task

CMD ["public/index.php"]

2. Not working Dockerfile:-

FROM bref/php-82-fpm

#COPY --from=bref/extra-redis-php-81:1 /opt /opt
#COPY --from=bref/extra-gmp-php-81:1 /opt /opt

COPY . /var/task

CMD ["Bref\LaravelBridge\Http\OctaneHandler"]

3. Error:- In cloud watch respective lambda function i am getting this error.

INIT_REPORT Init Duration: 24.44 ms Phase: init Status: error Error Type: Runtime.ExitError

entrypoint requires the handler name to be the first argument
