No description provided.

I don't see the code to set this attribute in the datasource.

[itakouna]

is not set in?

if err = d.Set("backend_server", flattenLoadbalancerBackendServers(loadbalancer.Properties.BackendServers)); err != nil {
		return fmt.Errorf("%s error setting BackendServers: %v", errorPrefix, err)
	}

otherwise how the test is passed.

@itakouna this function only does for "weight" and "host".

func flattenLoadbalancerBackendServers(backendServers []gsclient.BackendServer) []interface{} {
	tempBackendServers := make([]interface{}, 0)
	if backendServers != nil {
		for _, value := range backendServers {
			backendServer := map[string]interface{}{
				"weight": value.Weight,
				"host":   value.Host,
			}
			tempBackendServers = append(tempBackendServers, backendServer)
		}
	}
	return tempBackendServers
}

@itakouna oh I see you updated that function now. Github redirects me to the original function (before your change) when I click on the function name.
