Hey! I don't know why we do not have a "location" in the automation_dsc_nodeconfiguration resource, but in automation_dsc_configuration everything is fine (if the tests indicate the location is not East US, but eastus). In the nodeconfiguration file, we use the same with the logic of the configuration file:

func NewAzureRMAutomationDscNodeconfiguration(d *schema.ResourceData, u *schema.UsageData) *schema.Resource {

return &schema.Resource{

Name:           d.Address,

CostComponents: nodesCostComponent(d, u),

}

}

This is all logic in nodeconfiguration, we are using same cost component.
