Deployment failure on scaleSetTemplate

[FerAgo-Sys]

I applied this template today using the fully configurable deployment and I came across with the following error:

{"code":"DeploymentFailed","message":"At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/arm-deployment-operations for usage details.","details":[{"code":"BadRequest","message":"{\r\n "code": "TargetResourceIdIsImmutable",\r\n "message": "The autoscale setting 'autoscalewad' under resource group 'IT-SERVICES-MOODLE-RG' is referencing target resource '/subscriptions/425f3735-5409-429d-b7bb-4059cec7de32/resourceGroups/IT-SERVICES-MOODLE-RG/providers/Microsoft.Compute/virtualMachineScaleSets/vmss-hu7wlg'. The target resource reference is immutable. If you want to change it, please create a new autoscale setting with a different name."\r\n}"}]}

The Scale Set configurations were the following:

controllerVmSku: Standard_D16ds_v4
webServerType: nginx
autoscaleVmSku: Standard_D16ds_v4
autoscaleVmCountMax: 10
autoscaleVmCountMin: 1

I applied the same configuration (with the exact same parameters) on October 1th and it executed without any errors.

What could be the issue?

Thank you.
