PrePostDeployentv2 Script Error

Hi

I am using the Prepost deployment script however I am getting the following error

The script works fine with the predeployment set to true. It is just the post deployment that is failing.

Index operation failed; the array index evaluated to null.
PowerShell exited with code '1'.

I believe this is happening when Pushing Pipelines to a list

Any help would be much appreciated as I am looking to implement this at a client site.

I am using the [Version 2](https://github.com/Azure/Azure-DataFactory/blob/main/SamplesV2/ContinuousIntegrationAndDelivery/PrePostDeploymentScript.Ver2.ps1) script

Kind regards
Sarath
