Describe the bug I am trying to create defend for container integration with default settings and it is throwing these errors. I went to the UI, the integration was created successfully. doesnt look like i have passed the wrong variables?

To Reproduce Steps to reproduce the behavior:

1. terraform apply
2. See the error in the output '...'

Expected behavior

  name    = "cloud_defend"

  force   = true
  skip_destroy = true

  enabled             = true
  agent_policy_id     = var.agent_policy_id
  integration_name    = elasticstack_fleet_integration.defend.name
  integration_version = elasticstack_fleet_integration.defend.version
