Internal Server Error / Runtime.ExitError

[connerdassen]

I cannot get this to work whatsoever, and because of a lack of logs I don't know where it's going wrong.
I have a Laravel project that I want to deploy using the CDK like this:

this.backend = new PhpFpmFunction(this, `Backend-${STAGE}`, {
            handler: 'public/index.php',
            code: packagePhpCode('code/backend'),
            phpVersion: '8.3',
            vpc: props.vpc
}

It all deploys fine, but when visiting the resulting URL, I get an Internal Server Error, with the CloudWatch containins only this:

INIT_REPORT Init Duration: 404.55 ms	Phase: invoke	Status: error	Error Type: Runtime.ExitError
START RequestId: dc4f6c9f-eee8-44d2-82ea-317cda3ac07b Version: $LATEST
RequestId: dc4f6c9f-eee8-44d2-82ea-317cda3ac07b Error: Runtime exited with error: exit status 255 Runtime.ExitError

No further useful info at all.

I tried debugging locally using docker and found out the same Runtime.ExitError happened there, which was due to not having bref/bref and bref/laravel-bridge installed.

However, after installing, the error went away locally, but it still happens on Lambda after redeploying.
I did notice that when I download the code from lambda, the vendor directory only contains aws/ and autoload.php, not any of the dependencies. If I run locally on docker with only these present, I also get a Runtime.ExitError.

It seems that missing packages in vendor are indeed the problem; something causes packagePhpCode to not include anything other than vendor/aws and vendor/autoload.php.
After manually zipping and using lambda.Code.fromAsset, the lambda includes all packages in vendor and it works.

It seems to still not work perfectly, the invocation itself succeeds now, but I'm getting a 500 internal server error response on any path. CloudFront now looks like this:

with no output from PHP or Laravel at all.
