This filter works

data "nutanix_subnets_v2" "subnets" {
  filter = "name eq '${var.subnet}'"
  limit  = 1
}

This filter with multiple attributes fails.

data "nutanix_subnets_v2" "subnets" {
  filter = "name eq '${var.subnet}' and cluster_reference eq '${var.cluster_reference}'"
  limit  = 1
}

Debug Output

│ Error: error while fetching subnets : {"data":{"error":[{"$reserved":{"$fv":"v4.r0"},"$objectType":"networking.v4.error.AppMessage","message":"Failed to list subnets due to a bad request - Odata Error: Error while parsing URI","severity":"ERROR","code":"NETWORKING-10002","locale":"en_US"}],"$reserved":{"$fv":"v4.r0"},"$objectType":"networking.v4.error.ErrorResponse"},"$reserved":{"$fv":"v4.r0"},"$objectType":"networking.v4.config.GetSubnetApiResponse","metadata":{"flags":[{"$reserved":{"$fv":"v1.r0"},"$objectType":"common.v1.config.Flag","name":"hasError","value":true},{"$reserved":{"$fv":"v1.r0"},"$objectType":"common.v1.config.Flag","name":"isPaginated","value":false},{"$reserved":{"$fv":"v1.r0"},"$objectType":"common.v1.config.Flag","name":"isTruncated","value":false}],"$reserved":{"$fv":"v1.r0"},"$objectType":"common.v1.response.ApiResponseMetadata","links":[{"$reserved":{"$fv":"v1.r0"},"$objectType":"common.v1.response.ApiLink","href":"https://x.x.x.x:9440/api/networking/v4.0/config/subnets","rel":"self"}],"totalAvailableResults":0}}

Panic Output

Expected Behavior

Should find the subnet for the given cluster.

Actual Behavior

Above error

Steps to Reproduce

1. terraform apply

​

[tomrijnland]

Found a workaround so Terraform deals with the filter instead of the API or Provider.

data "nutanix_subnets_v2" "subnets" {
    filter = "name eq '${var.subnet}'"
  }

locals {
  filtered_data = [
    for subnet in data.nutanix_subnets_v2.subnets.subnets : subnet
    if subnet["cluster_reference"] == var.cluster
  ]

  ext_id = length(local.filtered_data) > 0 ? local.filtered_data[0]["ext_id"] : null
}`

Hi @tomrijnland ,

Correct filter is name eq '${var.subnet}' and clusterReference eq '${var.cluster_reference}'

Please refer https://developers.nutanix.com/api-reference?namespace=networking&version=v4.0#tag/Subnets/operation/listSubnets Query parameters sections for more attributes

[bhati-pradeep]

Attribute names are in camel case and supported filter attributes are below as per doc:

clusterReference
extId
isExternal
name
subnetType
vpcReference

@GullapalliAkhil @Haroon-Dweikat-Ntx Can we add some guide in docs for filters ?

[xerxist]

Im not sure if Terrafrom is the right place to directly make api calls like that. Now every time you have to look up the api calls reference. It feels very out of Terraform standards to work this way.

[bhati-pradeep]

I will note that down. We should have filters allowed attributes noted in provider docs. Will get that added 👍

[Haroon-Dweikat-Ntx]

Hi @xerxist

We will incorporate the allowed filter attributes into the provider documentation to clarify their usage. Thank you for bringing this to our attention!
