Getting error when update key vault using Terraform azapi

I am trying to upload a key vault secret value in terraform but getting error

resource "azapi_update_resource" "keyvault_secret_update_function_app_id" {
type                   = "Microsoft.KeyVault/vaults/secrets@2022-07-01"
resource_id            = "/subscriptions/myguid/resourceGroups/resource-group-name/providers/Microsoft.KeyVault/vaults/ali-test-remotely-kv-dev/secrets/remotely-managed"
response_export_values = ["*"]
body = jsonencode({
properties = {
  value = "test value"
}
})
}

I am getting following error

Update key vault secret using Terraform azapi

As per latest terraform_registry updating the keyvault secret using azapi should be done by passing the value directly in the body not by passing it as json.

sample configuration:

resource "azapi_update_resource" "keyvault_secret_update_function_app_id" {
  type        = "Microsoft.KeyVault/vaults/secrets@2022-07-01"
  resource_id = "/subscriptions/subID/resourceGroups/vinay-rg/providers/Microsoft.KeyVault/vaults/testssamplsvksb/secrets/testsample"
  response_export_values = ["*"]

  body = {
    properties = {
      value = "test value"
    }
  }
}
