Can't access attributes on a list of objects. Did you mean to access an attribute for a specific element of the list, or across all elements of the list?

Solution to the Problem for me: dynamic "volume" { for_each = each.value.template.volume == null ? [] : [each.value.template.volume]

  content {
    name         = volume.value[volume.key].name
    storage_name = volume.value[volume.key].storage_name
    storage_type = volume.value[volume.key].storage_type
  }
}

(Added volume.key)
