Terraform does not work input and environment variables

I have a glue job in aws. I made a loop.

In variables.tf

variable "list_of_jobs" {
  type = list(string)
  default = ["myjob1","myjob2","myjob3"]
}

In glue.tf

resource "aws_glue_job" "this" {
  for_each = toset(var.list_of_jobs)
  name     = each.value
  role_arn = var.role_arn

  command {
    name = "pythonshell"
    python_version = 3
    script_location = "s3://mybucket/${each.value}/run.py"
  }
}

In main.tf

variable "region" {}
variable "list_of_jobs" {}

module "my_glue" {
  source = "../terraform-glue"
  region = var.region
  list_of_jobs = var.list_of_jobs
}

This loop works fine, and I have 3 glue jobs after execution of terraform apply. The problem, when I am trying to make:

export TF_VAR_list_of_jobs='["myjob1","myjob2","myjob3"]'

In this case, when I am making terraform apply, I am receiving this:

Error: Invalid function argument

  on ../terraform-glue/glue.tf line 2, in resource "aws_glue_job" "this":
   2:   for_each = toset(var.list_of_jobs)
    |----------------
    | var.list_of_jobsis "[\"myjob1\",\"myjob2\",\"myjob3\"]"

Invalid value for "v" parameter: cannot convert string to set of any single
type.

Input variables, does not work too. Only variable from variables.tf. Could You help me please ? I am trying to resolve this during all night.

It does not work because you need to provide type constrain for your complex variable if you want to pass it though env variables:

variable "list_of_jobs" {
  type    = list(string)
  default = ["myjob1","myjob2","myjob3"]
}
