Terraform Providers AWS

i’m using version 0.14.8. any idea on how to get the aws_ami datasource to dynamically filter with a list or map? this is what i have below but does not work.

variable “filter-tags” {
type = map
}

data “aws_ami” “db_ami” {
most_recent = true
owners = [“self”]

dynamic “filter” {
for_each = var.filter-tags

content {
name = tag.key
values = tag.value
}
}

terraform plan

Error: Invalid value for module argument

on main.tf line 38, in module “ec2_cluster”:
38: filter-tags = {
39: “tag:os” = [“ubuntu”]
40: “tag:release” = [“bionic”]
41: “tag:Team” = [“dba”]
42: “tag:purpose” = [“goodpurpose”]
43: }

The given value is not suitable for child module variable “filter-tags”
defined at …/…/…/modules/services/elastic-cluster/variables.tf:142,1-23:
element “tag:release”: string required.

now i have it to where it’s saying " Your query returned no results." and errors out. if i uncomment the hard coded lines, it works fine. I just want to dynamically create them so that I can modularize my terraform scripts.

variable "filter_tags" {
  description = "Custom tags to set on the Instances in the ASG"
  type        = map(string)
  default     = {
    "os" = "ubuntu"
    "release" = "bionic"
    "Team" = "dba"
    "purpose" = "GoodPurpose"
  }

dynamic "filter" {

    for_each = var.filter_tags
    iterator = tag
    content {
      name = "tag:${tag.key}"
      values = ["tag.value"]
    }
  }


  #filter {
  #  name   = "tag:os"
  #  values = ["ubuntu"]
  #}

  #filter {
  #  name   = "tag:release"
  #  values = ["bionic"]
  #}

  #filter {
  #  name   = "tag:Team"
  #  values = ["dba"]
  #}

  #filter {
  #  name   = "tag:purpose"
  #  values = ["GoodPurpose"]
  #}
}

never mind, tag value was off so error was correct.
