Adding Safes to Privileged Cloud in Bulk

[Jflesc01]

Hello,
I am using the Safe-Management.ps1 script to try and add multiple safes at once to our new implementation of Privileged Cloud. When running the script, I am getting the following:

PS D:\CyberArk\Scripts> .\Safe-Management.ps1 -PVWAURL "https://Removed.id.cyberark.cloud/PasswordVault" -Add -FilePath "D:\CyberArk\Github-Files\BulkSafe-Test.csv"

Starting script (v2.1.6)
Error Logging on. Error: Source:; Message: Get-LogonHeader: Not Found
->Source:Microsoft.PowerShell.Commands.Utility; Message: The remote server returned an error: (404) Not Found.
PS D:\CyberArk\Scripts>

I did some research, but I am not gifted enough on how to correct the Get-LogonHeader: Not Found error above. I read something about needing to utilize another script on here called IdentityRefresh_5.1.ps1 in conjunction with IdentityAuth.psm1.

Unfortunately I don't understand the documentation enough to get that to run and connect. Seems like if I get IdentityRefresh_5.1.ps1 working, I would then be able to run the Safe_Management.ps1 script.

I just don't know what to put for these values or where to find them:

.\IdentityRefresh_5.1.1.ps1 -logonToken $srcToken -IdentityTenantURL "https://something.id.cyberark.cloud" [-GroupName "CyberArk - Vault Users"] [-UPN "User@lab.local] [-UUID "23b7f98c-60b4-4c01-a33f-4caa99472343"] [-UUIDArray @("23b7f98c-60b4-4c01-a33f-e4caa9947703","21b74328c-60b4-4c01-a33f-4caa99472343")]

Obviously I get the IdentityTenantURL, but not sure about the rest.
This would be huge for my rollout if someone could get me started.

Thank you.
