Problem creating an user, an eschedule for they and associate that eschedule to a pre-existing escalation policies.

[Zarzaparro]

I'm trying to create a user, an eschedule for him and associate that eschedule to a pre-existing escalation policies

This is the code that is working:

#New user creation
resource "pagerduty_user" "new_user" {
name = "Pedro Palotes"
email = "palotes@example.com"
role = "user"
}

#New eschedule for him and its association with the new user
resource "pagerduty_schedule" "new_user_schedule" {
name = "Schedule de Pedro Palotes"
description = "Horario de lunes a viernes de 8am a 6pm en horario de España"
time_zone = "Europe/Madrid" # Zona horaria de España

layer configuration

layer {
name = "Layer 1"
start = "08:00:00"
end = "18:00:00"
rotation_virtual_start = "2024-03-11T08:00:00"
rotation_turn_length_seconds = 86400
users = [pagerduty_user.new_user.id]
}
}

But this is the part that does not work:

#Associate that new schedule to varios pre-existence escalation policies
resource "null_resource" "associate_schedule_to_policy" {
triggers = {
schedule_id = data.pagerduty_schedule.new_user_schedule_data.id
name = each.value
for_each = var.escalation_policy_id
}
}

In the variables I have this set:
variable "escalation_policy_id" {
description = "Id de los escalation"
type = set(string)
}

And in the tfvars I have this set:
escalation_policy_id = ["PRDZEJ1", "P99R45N"]

But if I "Terraform plan" I get this error:

A data resource "pagerduty_schedule" "new_user_schedule_data" has not been declared in the root module.

What am I doing wrong?

THanks in advance.
