Looking to pass a map in terraform

i have a local yaml file.

  - owner: "terraform-service-account"
    principal: "sa-1234"
    resources:
      - resource_name: "be_serivicing"
        resource_type: "TOPIC"
        operation: "WRITE"
      - resource_name: "cjiscool"
        resource_type: "TOPIC"
        operation: "READ"
  - owner: "terraform-service-account-write"
    principal: "sa-948534"
    resources:
      - resource_name: "cjiscoolgroup"
        resource_type: "GROUP"
        operation: "READ"

Im looking to pass the values resource_name, resource_type, principal and operation to a module.

From my code I have an output

output "principals_resources" {


value = {for acl in local.acls : acl.owner => acl.resources}

}

which gives me output

Changes to Outputs:
  + principals_resources = {
      + terraform-service-account       = [
          + {
              + operation     = "WRITE"
              + resource_name = "be_serivicing"
              + resource_type = "TOPIC"
            },
          + {
              + operation     = "READ"
              + resource_name = "cjiscool"
              + resource_type = "TOPIC"
            },
        ]
      + terraform-service-account-write = [
          + {
              + operation     = "READ"
              + resource_name = "cjiscoolgroup"
              + resource_type = "GROUP"
            },
        ]
    }

When I add the for_each in the module initially Im getting two or more values inside the tuple which should be intended from the output.

module "acls" {
  source = "../acls"

for_each = {for acl in local.acls : acl.owner => acl.resources}

  resource_type = each.value.resource_type
  resource_name = each.value.resource_name
  principal     = each.value.principal
  operation     = each.value.operation

}

How can I pass each resource_name, resource_type, operation and principal to a module?

I have tried to output the first map values to another output that would be inputted into my module. Sorry if this question is confusing, Im new to terraform and need help

EDIT: Here is the module. its creating a confluent topic

resource "confluent_kafka_acl" "topic_write" {

  count = var.resource_type == "TOPIC" && var.operation == "WRITE" ? 1 : 0

  resource_type = "TOPIC"
  resource_name = var.resource_name
  pattern_type  = "LITERAL"
  principal     = "User:${var.principal}"
  host          = "*"
  operation     = "WRITE"
  permission    = "ALLOW"

}

& here is the error Im getting.

│   on main.tf line 12, in module "acls":
│   12:   resource_type = each.value.resource_type
│     ├────────────────
│     │ each.value is tuple with 2 elements

You have to flatten you acls:

locals {   
    acls_flat = merge([
        for owner, values in local.acls: {
            for resource in values.resources: 
               "${owner}-${resource.resource_name}" => {
                   "${owner}" = owner
                   principal = values.principal
                  "resource" = resource
               }   
        }
    ]...)
}

then

module "acls" {
  source = "../acls"

  for_each = local.acls_flat

  resource_type = each.value.resource.resource_type
  resource_name = each.value.resource.resource_name
  principal     = each.value.principal
  operation     = each.value.operation

}
