Exiting without providing any reason

[bkuhl]

I'm trying to use this project in a containerized fashion with Lambda (there's not a lot of docs for using Docker). I've been through the docs here and through Bref and am unsure what I'm missing/doing wrong. When processing lobs locally and within AWS I get the error:

{
    "errorMessage": "RequestId: 36907a63-97ff-478b-b1fd-630f060a8661 Error: Runtime exited without providing a reason",
    "errorType": "Runtime.ExitError"
}

Locally I'm able to use serverless invoke -f worker --file=sqs-queue-event.json to tell my local env to process the job. However both locally and in AWS that's the only feedback I get, with no errors or anything on the Laravel side. It just doesn't work 🤷 . Logs are configured to go to stderr locally and bugsnag/stderr in Lambda.

My Dockerfile:

FROM bref/php-80

ADD . /var/task

    # production-ready dependencies
RUN curl -s https://getcomposer.org/installer | php \
    && php composer.phar install  --no-interaction --optimize-autoloader --no-dev --prefer-dist --no-cache \
    && rm composer.phar

ENTRYPOINT ["php", "worker.php"]

My container is defined within the serverless architecture as:

functions:
  worker:
    reservedConcurrency: 10
    image: xxxxx.xxxxx.amazonaws.com/[project]:lambda-serverless
    events:
      # Declares that our worker is triggered by jobs in SQS
      -   sqs:
            arn: !GetAtt SendMessagesQueue.Arn
            # If you create the queue manually, the line above could be:
            # arn: 'arn:aws:sqs:us-east-1:1234567890:my_sqs_queue'
            # Only 1 item at a time to simplify error handling
            batchSize: 1
