Terraform import for accessrule does not work

I have the following Terraform objects

resource "fmc_access_policies" "AccessPolicyVar1" {
  default_action = "BLOCK"
  default_action_log_begin = false
  default_action_log_end = false
  name = "Dummy_Policy"
}

resource "fmc_access_rules" "AccessPolicyVar1AccessRuleVar1" {
  acp = fmc_access_policies.AccessPolicyVar1.id
  action = "ALLOW"
  category = "--Undefined--"
  enable_syslog = false
  enabled = true
  log_begin = false
  log_end = false
  log_files = false
  name = "test"
  section = "Mandatory"
  send_events_to_fmc = false
}

Both objects do exist on FMC, so I'm trying to import Access policy, which works.

% terraform import -input=false fmc_access_policies.AccessPolicyVar1 005056b0-b67d-0ed3-0000-004294967810
(...)
Import successful!

The resources that were imported are shown above. These resources are now in
your Terraform state and will henceforth be managed by Terraform.

Then I try to import access rule, which fails

% terraform import -input=false fmc_access_rules.AccessPolicyVar1AccessRuleVar1 005056b0-b67d-0ed3-0000-000268434637
