Empty 'action' results in error properties` is not expected here, it's read onlyschema validate : Bug?

[dcw77]

Be gentle, I'm not a Developer. I think I found a bug?

When I try to make a change to a setting using the azapi_resource_action if I use an action = "update" it fails. Seems to be adding 'update' to the end of the request.

performing action update of "Resource: (ResourceId \"/subscriptions/subscription-id/resourceGroups/rg-name/providers/Microsoft.DesktopVirtualization/hostPools/hp-avd-hostpool/sessionHosts/xx-xx-avda-01\" │ / Api Version \"2024-04-08-preview\")": PATCH │ https://management.azure.com/subscriptions/subsctiption/subscription-id/resourceGroups/rg-name/providers/Microsoft.DesktopVirtualization/hostPools/hp-avd-hostpool/sessionHosts/xx-xx-avda-01/update │ -------------------------------------------------------------------------------- │ RESPONSE 404: 404 Not Found │ ERROR CODE UNAVAILABLE │ -------------------------------------------------------------------------------- │ Response contained no body │ --------------------------------------------------------------------------------

resource "azapi_resource_action" "update_allow_new_session" {
  depends_on = [ azurerm_virtual_machine_extension.register_session_host ]
  for_each = toset(local.avdb_vm_names)

  type        = "Microsoft.DesktopVirtualization/hostPools/sessionHosts@2024-04-08-preview"
  resource_id = "/subscriptions/${data.azurerm_subscription.primary.subscription_id}/resourceGroups/${data.azurerm_resource_group.avd-pp.name}/providers/Microsoft.DesktopVirtualization/hostPools/${data.azurerm_virtual_desktop_host_pool.hostpool.name}/sessionHosts/${each.key}"
  action      = "update"
  method      = "PATCH"

  body = {
    
  "properties": {
    "allowNewSession": false
  }
  }
}

If I omit 'action' or leave it blank then VSCode complains that I am trying to perform an edit to a read only setting. However if I ignore it's complaints and run the plan and apply it then it is successful and the Session Hosts are put into Drain Mode as expected

resource "azapi_resource_action" "update_allow_new_session" {
  depends_on = [ azurerm_virtual_machine_extension.register_session_host ]
  for_each = toset(local.avdb_vm_names)

  type        = "Microsoft.DesktopVirtualization/hostPools/sessionHosts@2024-04-08-preview"
  resource_id = "/subscriptions/${data.azurerm_subscription.primary.subscription_id}/resourceGroups/${data.azurerm_resource_group.avd-pp.name}/providers/Microsoft.DesktopVirtualization/hostPools/${data.azurerm_virtual_desktop_host_pool.hostpool.name}/sessionHosts/${each.key}"
  action      = ""
  method      = "PATCH"

  body = {
    
  "properties": {
    "allowNewSession": false
  }
  }
}

Hi @dcw77 ,

Thank you for taking time to report this issue!

Yes, the error message comes from the VSCode extension, I'll work on improving it.
