Powershell pre provisioning One Drives on a M365 tenant

I'm new to PowerShell and trying to follow these instructions to pre provision OneDrives in bulk on a tenant

https://learn.microsoft.com/en-us/sharepoint/pre-provision-accounts#pre-provision-many-users-at-the-same-time

I connect to my tenant , create a text file with users and save to C drive then try and run the script but get these errors (see pic) any idea what I'm doing wrong? probably something really simple
