Terraform v1.5.6
on darwin_amd64
+ provider registry.terraform.io/oracle/oci v5.11.0

Affected Resource(s)

Terraform Configuration Files

module "instance" {
  source = "oracle-terraform-modules/compute-instance/oci"

  instance_count              = 1
  compartment_ocid            = var.compartment_id
  shape                       = "VM.Standard.A1.Flex"

}

Debug Output

Panic Output

Expected Behavior

Be able to specify a region separately to the provider config.

Actual Behavior

Uses region of provider at the time the instance was created even if changed later on.

Steps to Reproduce

1. terraform apply to create an instance.
2. Change provider region.
3. terraform apply
4. Should say no changes required.

Or just try to specify a different region than the provider. Apologies if this is already possible somehow and I've missed it!

Did you update the subnet ocid, so it matches something that exists in the new region? Also, is the data source refreshed first to target the image's new OCID for the new region?
