Not working

I tried creating a MWAA enivrement but it failed.

Here is the code used :

module "s3_bucket_mwaa" {
  source      = "git::https://git.cloud.safran/safrangrp/publiccloud/landingzone/shared-modules/terraform-aws-s3.git?ref=2.1.0"
  security    = var.security
  environment = var.environment
  company     = var.company
  service_id  = var.service_id
  name = "${var.custom_name}mwaabucket"
  force_destroy = true
  encryption_type = "s3"
}

module "mwaa" {
  source = "git::https://git.cloud.safran/safrangrp/publiccloud/landingzone/shared-modules-dev/terraform-aws-mwaa?ref=fix-sls"
  # -----------------------------------
  # NAMING BLOCKS
  # -----------------------------------
  resourceprefix = "mwaa"
  safran_region  = "eu2"
  zone           = "z1"
  environment    = "dev"
  app_name       = "sls_pipeline"
  freetext       = "addmwaa"

  # -----------------------------------
  # TAG MANDATORY BLOCKS
  # -----------------------------------
  company    = "sls"
  service_id = "sls10516"

  # -----------------------------------
  #  MWAA BLOCKS
  # ----------------------------------- 
  bucket_mwaa_arn           = module.s3_bucket_mwaa.arn
  region                    = "eu-west-3"
  webserver_access_mode     = "PRIVATE_ONLY"
  mwaa_max_workers          = 2
  dag_processing_logs_level = "INFO"
  scheduler_logs_level      = "INFO"
  task_logs_level           = "INFO"
  webserver_logs_level      = "INFO"
  worker_logs_level         = "INFO"
}

As you can see I created a branch in the repository shared-modules-dev/terraform-aws-mwa but this branch only fix some minor issues and I do not think this is the cause of the issue.

For information, the vpc of the account has 3 subnets only have the standard vpc endpoints (it should not be an issue as mentioned here).
