Terraform : VMExtensionProvisioningError. Failed to download all specified files

I am trying to provision a vm and promote it to domain controller through a powershell script by running through customscriptextension of AzureRM, but it is giving an unexpected network close error. I am importing the powershell script from a github repository to be run post deployment Here is the code:

Start by reviewing the Terraform configuration, especially azurerm_virtual_machine_extension, its fileUris entry, and commandToExecute. Compare the reported VMExtensionProvisioningError with the linked Windows Custom Script Extension troubleshooting guidance. The issue does not specify a repository change or a concrete acceptance condition, so the required contribution remains undefined.
