Debug Output

Panic Output

Expected Behavior

The resource is built as follow:

resource "oci_core_instance_pool" "instance_pool" { #Required compartment_id = data.oci_identity_compartments.pool_compartment_id.compartments[0].id instance_configuration_id = data.oci_core_instance_configurations.instance_configuration.instance_configurations[0].id placement_configurations { #Required availability_domain = var.ipool_properties.AD1_placement_configuration.availability_domain primary_subnet_id = data.oci_core_subnets.pool_subnet_ad1.subnets[0].id } placement_configurations { #Required availability_domain = var.ipool_properties.AD2_placement_configuration.availability_domain primary_subnet_id = data.oci_core_subnets.pool_subnet_ad2.subnets[0].id } placement_configurations { #Required availability_domain = var.ipool_properties.AD3_placement_configuration.availability_domain primary_subnet_id = data.oci_core_subnets.pool_subnet_ad3.subnets[0].id } size = var.ipool_properties.instance_pool_size #Optional display_name = var.ipool_properties.display_name freeform_tags = var.ipool_properties.freeform_tags

dynamic "load_balancers" { for_each = var.ipool_properties.load_balancer_attachment.lb_attachment_enable ? var.ipool_properties.load_balancer_attachment.lb_attachments_details : [] iterator = lb_attachment content{ #Required backend_set_name = lb_attachment.value.backend_set_name load_balancer_id = data.oci_load_balancer_load_balancers.app_load_balancers.load_balancers[0].id port = lb_attachment.value.port vnic_selection = lb_attachment.value.vnic_selection } } }

if you update one the following parameters:

• backend lb port
• remove lb from ipool
• lb attachment from ipool

applying terraform apply changes should be applied

Actual Behavior

No changes are executed. The issue happens only with the use of the dynamic block

Steps to Reproduce

1. configured the resource as reported above
2. apply changes on the content of the dynamic block suing terraform apply

Important Factoids
