Retrieve a value from Terraform variable

I would like to retrieve the value of the following pin_connection_details and pin_task_position from the variable below:

How do I retrieve it?

Below is the variable from which these values need to be retrieved:

variable "config_settings" {
  description = "Configuration settings for the Pinpoint"
  type = list(object({
    name                           = string
    area                           = string
    version                        = string
    pin_config = object({
      pin_encrypt           = optional(bool, false)
      pin_mode              = optional(bool, false)
      pin_types = map(object({
        pin_name                    = string
        pin_port                    = string
        pin_connection_details      = optional(string, null)
        timer = object({
          start = string
          stop  = string
        })
      }))
    })
    pin_tasks = list(object({
      pin_task_name                 = string
      pin_task_position             = optional(string, null)
    }))
  }))
}

How can I resolve this issue?

I extended a bit your example to show how it can be achied

variable "config_settings" {
  description = "Configuration settings for the Pinpoint"
  type = list(object({
    name    = string
    area    = string
    version = string
    pin_config = object({
      pin_encrypt = optional(bool, false)
      pin_mode    = optional(bool, false)
      pin_types = map(object({
        pin_name               = string
        pin_port               = string
        pin_connection_details = optional(string, null)
        timer = object({
          start = string
          stop  = string
        })
      }))
    })
    pin_tasks = list(object({
      pin_task_name     = string
      pin_task_position = optional(string, null)
    }))
  }))
  default = [{
    area = "area"
    name = "name"
    pin_config = {
      pin_encrypt = false
      pin_mode    = false
      pin_types = {
        "key" = {
          pin_connection_details = "pin_connection_details"
          pin_name               = "pin_name"
          pin_port               = "pin_port"
          timer = {
            start = "start"
            stop  = "stop"
          }
        }
      }
    }
    pin_tasks = [{
      pin_task_name     = "pin_task_name"
      pin_task_position = "pin_task_position"
    }]
    version = "version"
  }]
}

output "pin_connection_details" {
  value = var.config_settings[0].pin_config.pin_types["key"].pin_connection_details
}

output "pin_task_position" {
  value = var.config_settings[0].pin_tasks[0].pin_task_position
}

you can play with it using 'terraform plan'

❯ terraform plan

Changes to Outputs:
  + pin_connection_details = "pin_connection_details"
  + pin_task_position      = "pin_task_position"

Hope it helps
