Group membership gone missing after reapply

[spralexx]

Description

I created a user and group using Tofu. The user got added to the group according to my configuration. After changing a permission flag inside the group and running tofu apply again my user is not a member of the group anymore.

Group when running tofu applyinitially

resource "ionoscloud_group" "clusteraccess" {
  name                           = "k8s cluster access to ${ ionoscloud_k8s_cluster.devops_k8s_cluster.name }"
  create_datacenter              = false
  create_snapshot                = false
  reserve_ip                     = false
  access_activity_log            = false
  create_pcc                     = false
  s3_privilege                   = false
  create_backup_unit             = false
  create_internet_access         = false
  create_k8s_cluster             = false
  create_flow_log                = false
  access_and_manage_monitoring   = false
  access_and_manage_certificates = false
  manage_dbaas                   = false
  user_ids                = [ ionoscloud_user.patrick.id ] 
}

Group when running tofu applyagain

resource "ionoscloud_group" "clusteraccess" {
  name                           = "k8s cluster access to ${ ionoscloud_k8s_cluster.devops_k8s_cluster.name }"
  create_datacenter              = false
  create_snapshot                = false
  reserve_ip                     = false
  access_activity_log            = false
  create_pcc                     = false
  s3_privilege                   = false
  create_backup_unit             = false
  create_internet_access         = false
  create_k8s_cluster             = true
  create_flow_log                = false
  access_and_manage_monitoring   = false
  access_and_manage_certificates = false
  manage_dbaas                   = false
  user_ids                = [ ionoscloud_user.patrick.id ] 
}

Nothing else changed in my code. No manual changes has been done.

Expected behavior

I would expect the user not to be deleted from the group.

Environment

Terraform version:

OpenTofu 1.8.8

Provider version:

6.6.9

We'll fix it soon, meanwhile: try adding the group to the user instead, it should have the same result:

resource "ionoscloud_user" "patrick" {
  group_ids = [ionoscloud_group.clusteraccess.id]
}

Thanks!
