code: 400, message: Error updating volume - Cannot specify NFSv3 export policy rules for non-NFSv3 volume

[red73ver]

netapp-gcp provider version = "23.12.0"
terraform version = v1.7.5 ( linux_amd64 )

This particular version of provider (23.12.0) does have a problem to create or update NFSv4 volume:

  name           = "my-cvs-vol-nfs"
  region         = var.region
  protocol_types = ["NFSv4"]
  network        = data.google_compute_network.my_vpc.name
  volume_path    = "my-cvs-vol-nfs"
  size           = 100
  service_level  = "extreme"
  storage_class  = "hardware"

  export_policy {
    rule {
      allowed_clients = "10.0.1.0/24"
      access          = "ReadWrite"
      nfsv3 {
        checked = false
      }
      nfsv4 {
        checked = true
      }
    }
  }
}

It results in error

Error: code: 400, message: Error updating volume - Cannot specify NFSv3 export policy rules for non-NFSv3 volume

Problem also exist when terraform check existing volumes created using previous version of provider, and trying to remove and add exactly the same block of "export_policy" as below.

  - export_policy {
          - rule {
              - access               = "ReadWrite" -> null
              - allowed_clients      = "10.0.1.0/24" -> null
              - has_root_access      = "true" -> null
              - kerberos5_readonly   = false -> null
              - kerberos5_readwrite  = false -> null
              - kerberos5i_readonly  = false -> null
              - kerberos5i_readwrite = false -> null
              - kerberos5p_readonly  = false -> null
              - kerberos5p_readwrite = false -> null

              - nfsv3 {
                  - checked = false -> null
                }

              - nfsv4 {
                  - checked = true -> null
                }
            }
        }
      + export_policy {
          + rule {
              + access               = "ReadWrite"
              + allowed_clients      = "10.0.1.0/24"
              + kerberos5_readonly   = false
              + kerberos5_readwrite  = false
              + kerberos5i_readonly  = false
              + kerberos5i_readwrite = false
              + kerberos5p_readonly  = false
              + kerberos5p_readwrite = false

              + nfsv3 {
                  + checked = false
                }

              + nfsv4 {
                  + checked = true
                }
            }
        }

In this case terraform also fail with the same code as above.

Described problem exist only in 23.12.0 version of this provider. Version 23.4.0 seems to be completely fine.

I can confirm the issue. Additionally to the NFSv3/NFSv4 issue, plans are not stable since f3a8f75, which is bad.
