I am getting all external users for the site collection using below pnp powershell. It runs perfectly for some site collections.
$connection = Connect-PnPOnline -Url $siteurl -Tenant $TenantID -ClientId $AppID -Thumbprint $Thumbprint -ReturnConnection -WarningAction SilentlyContinue
write-output "Established connection "
$ctx = Get-PnPContext
$allusers = Get-PnPUser -Connection $connection | Where{$_.LoginName -like "_*#ext#*" -or $.LoginName -like "*urn:spo:guest*"}
But, I need to iterate over 600 000 site collections and for that I am calling 25 instances of the runbook at a time. On doing so, for some site collections , it gives below error
The collection has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested
on the get-pnpuser line and sometime during creating connection. Not sure what is causing this.
