The requested app service plan cannot be created in the current resource group because it is hosting Linux apps. Please choose a different resource group or create a new one.

When I am trying to deploy a new function app with a new resource group, I got this error:

The requested app service plan cannot be created in the current resource group because it is hosting Linux apps. Please choose a different resource group or create a new one.

But The resource group I'm using is a new one which has no resource there.

Here is a sample code snippet:

final FunctionApp.DefinitionStages.Blank functionApp = getAzureClient().appServices()
                .functionApps().define("twhublinux");
final NewAppServicePlanWithGroup newAppServicePlanWithGroup = functionApp.withRegion(Region.US_WEST);
final WithCreate withCreate = newAppServicePlanWithGroup.withNewResourceGroup("twhublinuxgroup")
                .withNewConsumptionPlan();
withCreate.create();

Is that because something wrong when parsing the name "twhublinux" / "twhublinuxgroup"?
