Site Url is not properly formed in Powershell?

Hi,

I've been trying to add files to a site on SharePoint Online via PowerShell

$SiteUrl = Get-SPOSite https://company.sharepoint.com/site1

However, every time i run the script i get this error:

Get-SPOSite : The site https://company.sharepoint.com/site1 is not properly formed.

I have connected to sharepoint with the Connect-SPOService command correctly.

What is wrong with the url?
Thanks
