Possible bug with serverlesss-compose.yml

[zgheibali]

Hello, I'm trying to deploy multiple services to localstack with serverless (specifically serverless compose - which is a serverless feature to run commands across multiple services in 1 shot)

folders structure:

- serverless-compose.yml
- services
      - service-a
              - lambdas
                         - hello (contains `handler.tsx`)
              - serverless.yml 
      - etc...

The file serverless-compose.yml contains:

services:
  service-a:
    path: ./services/service-a

Inside service-a, the file serverless.yml contains:

service: service-a

package:
  individually: true

custom:
  localstack:
    stages:
      - local

plugins:
  - serverless-localstack

provider:
  name: aws
  runtime: nodejs20.x
  region: us-east-1

functions:
  hello:
    handler: lambdas/hello/handler.handler
    timeout: 900

When I run serverless deploy --stage local to deploy to LocalStack at the serverless-compose.yml level, the command fails (not the case in a normal deployment to an AWS environment). And I got an error message "The specified bucket does not exist" (I attached an image with the error message for clarity)

When I try to deploy the same service to AWS without LocalStack:

What I tried to do:

Based on this: https://www.serverless.com/framework/docs/guides/deployment-bucket#3-deploying-with-compose, it seems that when using serverless compose, serverless tries to use 1 deployment bucket shared across services to simplify the process (instead of the standard a bucket per service when deploying without serverless compose). I tried creating a custom bucket in LocalStack and added the bucket to serverless.yml as follows:

# serverless.yml file

provider:
  name: aws
  runtime: nodejs20.x
  region: us-east-1
  deploymentBucket:
    name: custom-deployment-bucket

But this didn't work, and I still got the same error message, "The specified bucket does not exist"

Any help is appreciated.
