AD deployment Mandatory Parameter is missing

Template Issue: Mandatory parameter DomainName is missing.
Template: CreateADPDC.ps1
"message": "The DSC Extension failed to execute: Mandatory parameter DomainName is missing.

### Issue Details
I'm trying to deploy an active directory server using DSC for learning I have created my own JSON
The error That I get is this one "**Mandatory parameter DomainName is missing**", I'm sure I have defined the parameter domain name in my parameter file and in the azuredeploy.json but I don't know how to get rid of this error, I had attach the ps1, json files and the 0.status file output for the VM.

[azuredeploy.parameters.json.txt](https://github.com/Azure/azure-quickstart-templates/files/2502154/azuredeploy.parameters.json.txt)

[0.status.txt](https://github.com/Azure/azure-quickstart-templates/files/2502167/0.status.txt)

[CreateADPDC.ps1.txt](https://github.com/Azure/azure-quickstart-templates/files/2502172/CreateADPDC.ps1.txt)

Start by comparing how DomainName is declared and passed across CreateADPDC.ps1, azuredeploy.json, and azuredeploy.parameters.json, then inspect 0.status.txt for the DSC Extension invocation. Done means the template deploys the Active Directory server without the mandatory-parameter error.
