Unknown application error occurred Runtime.Unknown

[TheSupremeBeard]

I am trying to run an SQS Queue using Bref and Laravel. I am currently getting the error "Unknown application error occurred Runtime.Unknown" in the Cloudwatch logs. I'm pretty sure i've followed the instructors correctly in the docs but don't seem to be having a good time.

I have added the following construct to my serverless.yml file

constructs:
  jobs:
    type: queue
    worker:
      handler: Bref\LaravelBridge\Queue\QueueHandler
      runtime: php-81
      timeout: 28 # seconds

and i have the following in my provider: section

environment:
    SQS_QUEUE: ${construct:jobs.queueUrl}

Any help would be nicely appreciated

[mnapoli]

Could you detail which version of Bref, the laravel bridge and PHP you are using?

[TheSupremeBeard]

Thanks for the swift reply, ofc:

PHP 8.1 "bref/bref": "^2.0", "bref/laravel-bridge": "^2.1",

[mnapoli]

OK that looks good 🤔

Can you post the entire serverless.yml (redacting any sensitive information)?

Also do you have more details on what is logged in CloudWatch? Any extra info?

[TheSupremeBeard]

Sure here is the entire serverless file:

And this is what we see in CloudWatch on the worker:

[mnapoli]

Thanks, I tried your serverless.yml file locally but it seemed to generate something OK.

Could you try running serverless print and pasting the output here as well?

There should be a function with this kind of config:

  jobsWorker:
    handler: Bref\LaravelBridge\Queue\QueueHandler
    runtime: provided.al2
    timeout: 28

From my experience, the issue is with bref + a SQS consumer (I'm using Symfony messenger, you're using Laravel). So it's really about how bref endpoint is summoned by the SQS trigger.

I'll just share my solution (it's just an idea but it might quickfix that issue if it's blocking you).

Build a NodeJS lambda to process the SQS queue. And let the NodeJS lambda invoke another lambda. This lambda can be a simple PHP command with some arguments.

I believe that might work but I'll need a bit of time to refactor in that shape.

[LorenzoRogai]

Also happened to me. A PHP error inside the class caused the problem

[ThomasLabstep]

Could confirm it's working when using Node to consume the SQS queue and then invokeLambda the Symfony command with some data.

Something is definitely broken with the SQS event and bref.

[mnapoli]

@ThomasLabstep if you have a reproducible example that would be great!

[curlysanders]

I am encountering the same issue. Running the consumer locally by passing an event manually works.

Running:

• PHP: 8.2.7
• bref/bref: 2.1.1
• bref/symfony-bridge: 0.2.2
• bref/symfony-messenger: 0.5.4
• symfony/*: 6.3.3
• serverless framework: 3.34.0

Ignore my previous post. I have it working now. Didn't include the VPC in the worker lambda 😬

Thx for your excellent work @mnapoli!

[mnapoli]

I finally managed to reproduce and figure it out! Fix coming in #1616

It turns out in the sparse output we get, we actually get the exception message. But Laravel's exception message only contains a class name, so the logs don't make any sense at all.

Anyway, I'm refactoring those logs entirely, we'll have pleeeenty of explanation now!
