azapi_update_resource - ProviderError

[eberkut]

I have a terraform module which tags multiple resources at once passed as a list of resource ids. The main part of the code is:

locals {
  standard_tags = {
    "${var.tag_prefix}-deployedby"  = var.deployedby
  }

  # Static count-based keys for resource IDs
  resource_count = length(var.resource_ids)
  resource_keys  = toset([for i in range(local.resource_count) : tostring(i)])
}

# Merging Tags Logic
resource "azapi_update_resource" "merge_tags" {
  for_each = var.merge_tags ? { for idx in local.resource_keys : idx => var.resource_ids[idx] } : {}

  type      = "Microsoft.Resources/tags@2022-09-01"
  name      = "default"
  parent_id = each.value

  body = jsonencode({
    properties = {
      tags = local.standard_tags
    }
  })
}

This is inspired by #365 and is in line with Microsoft documentation in https://learn.microsoft.com/en-us/azure/templates/microsoft.resources/tags?pivots=deployment-language-terraform.

It works flawlessly on all my resources except OpenAI were I'm getting a ProviderError during apply:

  # module.tagging.azapi_update_resource.merge_tags["4"] will be created
  + resource "azapi_update_resource" "merge_tags" {
      + body                    = jsonencode(
            {
              + properties = {
                  + tags = {
                      + ait-deployedby  = "Terraform"
                    }
                }
            }
        )
      + id                      = (known after apply)
      + ignore_casing           = false
      + ignore_missing_property = true
      + name                    = "default"
      + output                  = (known after apply)
      + parent_id               = "/subscriptions/REDACTED_SUBSCRIPTION_ID/resourceGroups/rg-experimentation-01/providers/Microsoft.CognitiveServices/accounts/myopenai-dev-01"
      + resource_id             = (known after apply)
      + type                    = "Microsoft.Resources/tags@2022-09-01"
    }

However, the tags are still properly applied. And if I try with az rest, there's no error so we can rule out an issue with Azure API itself.

az rest --method put \
  --uri "https://management.azure.com/subscriptions/REDACTED_SUBSCRIPTION_ID/resourceGroups/rg-experimentation-01/providers/Microsoft.CognitiveServices/accounts/myopenai-dev-01/providers/Microsoft.Resources/tags/default?api-version=2022-09-01" \
  --body '{
    "properties": {
      "tags": {
        "ait-deployedby": "azure-cli"
      }
    }
  }'

With TF_LOG set to DEBUG, this is apparently the request/response that fails:

As can be seen in the logs, using Terraform 1.5.7 and terraform-provider-azapi 1.12.1.

Hi @eberkut ,

Thank you for taking time to report this issue!

I believe this is an upstream-api issue, I've created an issue to track it: Azure/azure-rest-api-specs#28209
