Lambda Container Error on /var/task/vendor/autoload.php

[wheeleruniverse]

Description:
I am trying to deploy my php web application in a serverless architecture using AWS Lambda. I am trying to utilize the new feature for containerized support on Lambda as opposed to the previous method of deploying Bref as a Lambda Layer.

I followed the instructions in this Blog post: https://mnapoli.fr/aws-lambda-php-docker-containers/, but when I deployed my container on Lambda I am getting the following error on invocation.

 PHP Fatal error:  require(): Failed opening required '/var/task/vendor/autoload.php' 
 (include_path='.:/opt/bref/lib/php') in /opt/bootstrap on line 17

Running docker run on my local laptop is also throwing the same error.

Here is my repository so you can see I am including everything inside this php directory in my docker container.
https://github.com/wheelers-websites/CloudGuruChallenge_1020/tree/master/php

How to reproduce:

• AWS Service: Containerized Lambda
• Bref Version: bref/php-74-fpm

1. Create Docker Image

FROM bref/php-74-fpm
COPY . /var/task
CMD _HANDLER=index.php /opt/bootstrap

2. Run Docker Image

docker run

Sorry the blog post is incomplete, I assumed something that may not be obvious to everyone 😅

You need to install bref in your project via:

composer require bref/bref

first. That will create a composer.json file and vendor/ directory.

Let me know if that works better.

Thanks! When I updated my Dockerfile to the following it's seemingly working now.

FROM bref/php-74-fpm
RUN curl -s https://getcomposer.org/installer | php
RUN php composer.phar require bref/bref
COPY . /var/task
CMD _HANDLER=index.php /opt/bootstrap

I am currently seeing below, but I haven't created the API Gateway yet. I will do that next. Thank you!

"errorType": "Bref\\Event\\InvalidLambdaEvent",
"errorMessage": "This handler expected to be invoked with a API Gateway or ALB event. Instead, the handler was invoked with invalid event data: Array\n(\n)\n",

Hi,
it seems that the error also happens when vendor is in another directory ? like https://github.com/Cockpit-HQ/Cockpit

composer.json

"config": {
       "vendor-dir": "lib/vendor",
       "optimize-autoloader": true,
       "prefer-dist": true,
       "lock": false,
       "ignore-platform-reqs": true
   }

serverless.yml

plugins:
    - ./lib/vendor/bref/bref

cloudwatch log : Fatal error: Uncaught Error: Failed opening required '/var/task/vendor/autoload.php' (include_path='.:/opt/bref/lib/php') in /opt/bootstrap:37

@stloc check out https://bref.sh/docs/environment/php.html#custom-vendor-path

[stloc]

thanks and sorry Matthieu I should have read the documentation better !

[mnapoli]

No problem at all!

[mnapoli]

That makes me think that we could actually improve the error message in that case! The error message could contain a link to that documentation page, that would be much better 🤔

I won't have time to work on this soon, but if you want to submit a PR feel free.
