Unable to invoke console command via "aws lambda invoke"

[fbuchlak]

Description:

I'm trying to run symfony "bin/console" command like described in documentation.

How to reproduce:
Running command

aws lambda invoke \
    --function-name PhpCliLambdaName \
    --region us-east-1 \
    --cli-binary-format raw-in-base64-out \
    --payload '"d:s:u --dump-sql"' \
    response.json

returns

{
    "StatusCode": 200,
    "FunctionError": "Unhandled",
    "ExecutedVersion": "$LATEST"
}

and logs this

{
    "errorType": "TypeError",
    "errorMessage": "Bref\\Runtime\\FileHandlerLocator::{closure}(): Argument #1 ($context) must be of type array, string given, called in /var/task/vendor/bref/bref/src/Runtime/Invoker.php on line 29",
    "stack": [
        "#0 /var/task/vendor/bref/bref/src/Runtime/Invoker.php(29): Bref\\Runtime\\FileHandlerLocator->{closure}('d:s:u --dump-sq...', Object(Bref\\Context\\Context))",
        "#1 /var/task/vendor/bref/bref/src/Runtime/LambdaRuntime.php(89): Bref\\Runtime\\Invoker->invoke(Object(Closure), 'd:s:u --dump-sq...', Object(Bref\\Context\\Context))",
        "#2 /var/task/vendor/bref/bref/src/FunctionRuntime/Main.php(37): Bref\\Runtime\\LambdaRuntime->processNextEvent(Object(Closure))",
        "#3 /opt/bref/bootstrap.php(17): Bref\\FunctionRuntime\\Main::run()",
        "#4 {main}"
    ]
}

CDK

package.json

"@bref.sh/constructs": "^1.0.0",

brefStack.ts

this.fpm = new PhpFpmFunction(this, 'PhpFpm', {
  code,
  handler: 'public/index.php',
  timeout: Duration.seconds(20),
  ...lambdaProps,
});

this.cli = new ConsoleFunction(this, 'PhpCli', {
  code,
  handler: 'bin/console',
  timeout: Duration.seconds(120),
  ...lambdaProps, // contains architecture, environment, role, securityGroups, vpc and vpcSubnets
});

Symfony - code

composer.json (symfony 6.3)

"bref/bref": "^2.0",
"bref/symfony-bridge": "0.2.1",
"symfony/runtime": "6.3.*"

bin/console

#!/usr/bin/env php
<?php

use App\Kernel;
use Symfony\Bundle\FrameworkBundle\Console\Application;

if (!is_file(dirname(__DIR__).'/vendor/autoload_runtime.php')) {
    throw new LogicException('Symfony Runtime is missing. Try running "composer require symfony/runtime".');
}

require_once dirname(__DIR__).'/vendor/autoload_runtime.php';

return function (array $context) {
    $kernel = new Kernel($context['APP_ENV'], (bool) $context['APP_DEBUG']);

    return new Application($kernel);
};

I've already tried to send payload as json object with APP_ENV, APP_DEBUG, but in this case I'm not able to figure out how should I provide command.
Changing $context to string and creating Kernel with $_SERVER doesn't help either.

I was able to execute command with modified bin/console and payload {"command":"d:s:u", "--force": true}, but this time lambda could not return response and timed out (but schema did update).

#!/usr/bin/env php
<?php

use App\Kernel;
use Symfony\Bundle\FrameworkBundle\Console\Application;

if (!is_file(dirname(__DIR__).'/vendor/autoload_runtime.php')) {
    throw new LogicException('Symfony Runtime is missing. Try running "composer require symfony/runtime".');
}

require_once dirname(__DIR__).'/vendor/autoload_runtime.php';

return function (array $context) {
    $kernel = new Kernel($_SERVER['APP_ENV'], (bool) $_SERVER['APP_DEBUG']);

    $application = new Application($kernel);

    $input = new Symfony\Component\Console\Input\ArrayInput($context);
    $output = new Symfony\Component\Console\Output\BufferedOutput();

    $application->run($input, $output);

    return new Symfony\Component\HttpFoundation\Response($output->fetch());
};

Looking at ConsoleRuntime I'm clearly missing "event". But how can I provide it?

It seems like you have modified bin/console: you shouldn't. You don't need to adapt this file for Lambda/Bref.

You should leave this file like on any standard Symfony installation, the "console" runtime takes care of executing it.

[fbuchlak]

Thank you for your reply, but actually the first provided snippet for bin/console is original source code (since symfony version 5.3). See https://github.com/symfony/demo/blob/main/bin/console

Error occurs with clean installation of symfony skeleton application (6.3) and cdk construct ConsoleFunction from @bref.sh/constructs.

However looking at the stack trace now I don't see previously mentioned ConsoleRuntime/Main.php as it directly falls into FunctionRuntime/Main.php from main. Seems like there is problem with running correct runtime.

[fbuchlak]

Figured it out. The problem is that ConsoleFunction constructs creates 2 layers. Specifically function layer for php and console layer. As stated in PhpFpmFunction the php layer should be first, so console layer can override it.
However lambda created by aws cdk had console layer created as first.

[mnapoli]

Ohhh thanks for investigating further! It seems related to brefphp/constructs#4, which I can't reproduce for some reason! I need to figure this out 🤔

Seem's that i'm having the same output when trying to run https://bref.sh/docs/runtimes/function sample in PHP with Symfony

This seem's to be related to this discussion.

Thanks for the discussion and hope this can bring more informations to make it reproductible.

@matyo91 this isn't related to the AWS CDK constructs. In your case you are invoking the following function:

    hello:
        handler: my-function.php
        runtime: php-81-fpm
        events:
            - httpApi: '*'

like it's an event-driven function. But it's using the php-81-fpm runtime (it even has HTTP events), it's an HTTP Lambda, not a "function" Lambda. (this is why it expects an HTTP event, and it's causing an error)

If you want to invoke it locally you should look at this guide instead: https://bref.sh/docs/local-development

Or if you absolutely want to use bref:local, this section of the "bref:local" docs should help: https://bref.sh/docs/local-development/event-driven-functions#api-gateway-local-development (but it's advanced, I wouldn't do that).
