Limitation on the number of characters in the resource ibm_resource_tag

Terraform CLI and Terraform IBM Provider Version

Terraform v1.0.3
on darwin_amd64
+ provider registry.terraform.io/ibm-cloud/ibm v1.40.0

Error

The ibm_resource_tag resource has a limitation in the resource_id parameter of 128 characters, the problem is that there are some ibm cloud resources that their crn is longer than 128 characters.

resource "ibm_resource_tag" "tag" {
    resource_id = ibm_satellite_location.location.crn
    tags        = var.tag_names
}

To reproduce this error you can run the following template:

resource "ibm_database" "elasticsearch" {
  resource_group_id            = data.ibm_resource_group.resource_group.id
  name                         = "test"
  service                      = "databases-for-elasticsearch"
  plan                         = "standard"
  location                     = "eu-de"
  members_disk_allocation_mb   = 61440
  members_memory_allocation_mb = 43008
  tags                         = ["one:two"]
  whitelist {
    address     = "172.168.1.2/32"
    description = "desc1"
  }
  timeouts {
    create = "120m"
    update = "120m"
    delete = "15m"
  }
}

data "ibm_resource_tag" "current" {
  resource_id = ibm_database.elasticsearch.id
}

resource "ibm_resource_tag" "update" {
  resource_id = ibm_database.elasticsearch.id
  tags        = ["two:three"]
}

The output error:

terraform apply 

ibm_database.elasticsearch: Refreshing state... [id=crn:v1:bluemix:public:databases-for-elasticsearch:eu-de:*/******************:*******************:::]
Error: "resource_id" ("crn:v1:bluemix:public:databases-for-elasticsearch:eu-de:*/******************:*******************::") must contain from 1 to 128 characters
with data.ibm_resource_tag.current,
on main.tf line 59, in data "ibm_resource_tag" "current":
59:   resource_id = ibm_database.elasticsearch.id

Solution

The solution would be to increase the resource_id characters to accept more than 128 characters.
