TF vsphere -> vsphere_content_library_item - upload error


Any ideas why my code is failing?

resource "vsphere_content_library_item" "xxx" {
  name        = "2016"
  description = "ISO for Windows 2016"
  file_url    = "https://xxxx/2016.iso"
  library_id  =
  type = "iso"


**The plugin.(*GRPCProvider).ApplyResourceChange request was cancelled.**

Via GUI, I am able to upload ISO to Content Library via the same URL as I have in the code. So, connection is fine, only TF has some problem with that.
