First Steps: Internal Server Error 500

[kavatari]

Description:

Following this guide: https://bref.sh/docs/first-steps.html
I want to run the simple "Hello World" example. After deploying the app to AWS Lambda and calling the url, I receive the error 500 with the message: {"message":"Internal Server Error"}

How to reproduce:
Installed bref version (using composer): 1.2.6

composer require bref/bref
vendor/bin/bref init
serverless deploy

serverless.yml

service: app
provider:
  name: aws
  region: us-east-1
  runtime: provided.al2
plugins:
  - ./vendor/bref/bref
functions:
  api:
    handler: index.php
    description: ''
    timeout: 28 # in seconds (API Gateway has a timeout of 29 seconds)
    layers:
      - ${bref:layer.php-74-fpm}
    events:
      - httpApi: '*'
# Exclude files from deployment
package:
  exclude:
    - 'node_modules/**'
    - 'tests/**'

Saw this closed issue: #390 but it doesn't help.

@kavatari this is most likely because you use php 8.0 locally and the serverless.yml is using the 7.4 layer ${bref:layer.php-74-fpm}. Replace it by the 8.0 layer ${bref:layer.php-80-fpm}

When using Bref (and Lambda in general), you can see the logs in Cloudwatch > Log groups and you should see the error.

Note that if you need support, you can use the Github discussion or join the Slack (see https://bref.sh/docs/community.html)

Hey, really sorry about the poor experience here.

To find where the error is coming from, please run:

serverless logs -f api

That will show the logs of the api function. If there are no logs, open up the web page to trigger an "Internal error", and run the command again after a few seconds.

FYI that kind of error is a generic "server error", that means there's an error in the PHP code for some reason.
