cors_rule problem

[Alex]

Description

I wan't to create one S3 bucket with cors_rule rule information, but getting error.

Versions

• Terraform:Terraform v0.12.7
• Terragrunt: terragrunt version v0.28.18
• Provider(s): don't have idia, bevause installet only terraform and terragrunt using brew install
• Module: source = "git::[e-mail]:terraform-aws-modules/terraform-aws-s3-bucket.git?ref=v1.6.0"

Reproduction

Steps to reproduce the behavior:

1. create aws test account
2. create user for s3 without any roles assing as wit application access
3. copy arn ot the user
4. save my code and replace user arnin ${dependency.apple-iam.outputs.s3-user-ui_arn}
5. try run terragrun apply in . with my code

Code Snippet to Reproduce

terraform {
  source = "git::[e-mail]:terraform-aws-modules/terraform-aws-s3-bucket.git?ref=v1.6.0"
}

dependencies {
  paths = ["../aws-data" , "../apple-iam"]
}

dependency "apple-iam" {
  config_path = "../apple-iam"
}

include {
  path = find_in_parent_folders()
}

            ]
        },

                "arn:aws:s3:::terraform-apple-ui"
            ]
        }
    ]
})

cors_rule = [
    {
      allowed_methods = ["PUT", "POST"]
      allowed_origins = ["https://modules.tf", "https://terraform-aws-modules.modules.tf"]
      allowed_headers = ["*"]
      expose_headers  = ["ETag"]
      max_age_seconds = 3000
      }, {
      allowed_methods = ["PUT"]
      allowed_origins = ["https://example.com"]
      allowed_headers = ["*"]
      expose_headers  = ["ETag"]
      max_age_seconds = 3000
    }
  ]

}

Expected behavior

should create S3 with filled cors_rule from field cors_rule in terracgrunthcl

Actual behavior

error on terragrunt apply or\and terragrunt apply-all

Error: Invalid function argument

on main.tf line 25, in resource "aws_s3_bucket" "this":
25: for_each = length(keys(var.cors_rule)) == 0 ? [] : [var.cors_rule]
|----------------
| var.cors_rule is tuple with 2 elements

Invalid value for "inputMap" parameter: must have map or object type.

Additional information only after todays Anton stream, i realized that i can try migrate to terraform 13.1, i've done it and with jsonencode() this part start wokring fine.

part of the code for cors_rule:

cors_rule = jsonencode([
    {
      allowed_methods = ["PUT", "POST"]
      allowed_origins = ["https://modules.tf", "https://terraform-aws-modules.modules.tf"]
      allowed_headers = ["*"]
      expose_headers  = ["ETag"]
      max_age_seconds = 3000
      }, {
      allowed_methods = ["PUT"]
      allowed_origins = ["https://example.com"]
      allowed_headers = ["*"]
      expose_headers  = ["ETag"]
      max_age_seconds = 3000
    }
  ])

anyway, thanks Anton for the new release and today's stream on youtube on your channel.
