Schema validation fails when using azapi_resource for keyvault with random string in the name

[bengodeloson]

We are currently using azapi_resource for our keyvault. Upon upgrading the provider from 1.12.1 to 1.13.0 and 1.13.1, we encounter an issue which has this error:

##[error][TerraformClient]: Terraform command finished with errors: ╷
│ Error: Invalid configuration
│
│ with module.keyvault.azapi_resource.key_vault,
│ on tempSource/akv.tf line 5, in resource "azapi_resource" "key_vault":
│ 5: resource "azapi_resource" "key_vault" {
│
│ embedded schema validation failed: the argument "body" is invalid:

│ You can try to update azapi provider to the latest version or disable the validation using the feature flag schema_validation_enabled = false within the resource block
╵

We are adding random string in our keyvault name which has the following configuration:

resource "random_string" "akv_suffix" {
  length  = 3
  special = false
  upper   = false
}

resource "azapi_resource" "key_vault" {
  type      = "Microsoft.KeyVault/vaults@2022-07-01"
  name      = "akv${var.name}${random_string.akv_suffix.result}"
  location  = var.location
  parent_id = local.resource_group_id
  tags      = local.tags
...
}

When we remove the ${random_string.akv_suffix.result} or disabling the schema validation, the plan stage succeeds. We really want to add the schema validation to our module and this was working previously in 1.12.1. Can anyone help us with this issue?

Hi @bengodeloson ,

Thank you for taking time to report this issue!

I'll fix it in the next release. As a workaround, please disable the scheme validation and you could enable it after the bug fix is released.
