Expected Behavior

I have an existing endpoint successfully created that looks like this:

module.discuss_cluster.azurerm_cdn_endpoint.app:
  id = /subscriptions/xxxx/resourcegroups/xxxx-dev-michael-discuss/providers/Microsoft.Cdn/profiles/discuss/endpoints/xxxx-dev-michael-discuss
  content_types_to_compress.# = 0
  geo_filter.# = 0
  host_name = xxxx-dev-michael-discuss.azureedge.net
  is_compression_enabled = false
  is_http_allowed = true
  is_https_allowed = true
  location = eastus
  name = xxxx-dev-michael-discuss
  optimization_type = GeneralWebDelivery
  origin.# = 1
  origin.722596397.host_name = xxxxdevmichaeldiscuss.blob.core.windows.net
  origin.722596397.http_port = 80
  origin.722596397.https_port = 443
  origin.722596397.name = assets
  origin_host_header = xxxxdevmichaeldiscuss.blob.core.windows.net
  origin_path = /assets/
  probe_path = 
  profile_name = discuss
  querystring_caching_behaviour = IgnoreQueryString
  resource_group_name = xxxx-dev-michael-discuss
  tags.% = 2
  tags.Cluster = discuss
  tags.DC = xxxx-dev-michael

I attempted to introduce a change by commenting origin_path and re-running terraform apply but terraform didn't detect the change.

Actual Behavior

"No changes. Infrastructure is up-to-date."

Steps to Reproduce

1. comment out origin_path
2. terraform apply

Setting it explicitly to "" also did not cause a change.

I had to set it to another value ("/") to force the change (though / is invalid here so it didn't apply):

Terraform will perform the following actions:

  ~ module.discuss_cluster.azurerm_cdn_endpoint.app
      origin_path: "/assets/" => "/"
