Unable to run command using Azure scale set extension for Windows - azure

Question

I am using terraform to Launch some Azure Scale set for windows. I have wrote below code for updating the dynamic IP of the VM created by the terraform.
publisher = "Microsoft.Compute"
settings = jsonencode({
commandToExecute = "powershell.exe (((Get-Content -path C:\\Nomad\\agent\\agent.hcl -Raw) -replace '108.98.16.4','${data.azurerm_network_interface.main.private_ip_address}'| Set-Content -Path C:\\Nomad\\agent\\agent.hcl) | sc.exe start Nomad"
})
But its throwing below error :
Error: Code="VMExtensionProvisioningError" Message="VM has reported a
failure when processing extension 'joinNomadNodes'. Error message:
\"Command execution finished, but failed because it returned a
non-zero exit code of: '255'. The command had an error output of:
''Set-Content' is not recognized as an internal or external
command,\r\noperable program or batch file.\r\n'\"\r\n\r\nMore

Now if i am running the command manually its running without any error:
powershell.exe (((Get-Content -path C:\\Nomad\\agent\\agent.hcl -Raw) -replace '108.98.16.4','178.98.16.5'| Set-Content -Path C:\\Nomad\\agent\\agent.hcl) | sc.exe start Nomad"

Answer 1

I have added the escape char "^" just before the "|" .. Now its running fine.
publisher = "Microsoft.Compute"
settings = jsonencode({
commandToExecute = "powershell.exe (((Get-Content -path C:\Nomad\agent\agent.hcl -Raw) -replace '108.98.16.4','${data.azurerm_network_interface.main.private_ip_address}'^| Set-Content -Path C:\Nomad\agent\agent.hcl) ^| sc.exe start Nomad)"
})
