SharePoint Online, creating multiple list with pnp PowerShell errors out

Question

I am building a site creation script in PowerShell working good for now.

I added a part to create lists and add to navigation depending on what kind of site is selected.

`

          Connect-PnPOnline -Url $NewSiteUrl -Credentials $cred
            New-PnPList -Title Newsfeed -Template DiscussionBoard
            New-PnPList -Title Tasks -Template Tasks
            New-PnPList -Title Contacts -Template Contacts
            New-PnPList -Title Calendar -Template Events
            New-PnPList -Title Links -Template Links 
            Add-PnPNavigationNode -Title "Newsfeed" -Url "$NewSiteUrl/Lists/Newsfeed" -Location "QuickLaunch"
            Add-PnPNavigationNode -Title "Tasks" -Url "$NewSiteUrl/Lists/Tasks" -Location "QuickLaunch"
            Add-PnPNavigationNode -Title "Contacts" -Url "$NewSiteUrl/Lists/Contacts" -Location "QuickLaunch"
            Add-PnPNavigationNode -Title "Calendar" -Url "$NewSiteUrl/Lists/Calendar" -Location "QuickLaunch"
            Add-PnPNavigationNode -Title "Links" -Url "$NewSiteUrl/Lists/Links" -Location "QuickLaunch"
            Add-PnPNavigationNode -Title "Manage Site Access" -Url "$NewSiteUrl/_layouts/groups.aspx" -Location "QuickLaunch"

` While the script runs I get this error when it goes through this section:

format-default : 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. + CategoryInfo : NotSpecified: (:) [format-default], CollectionNotInitializedException + FullyQualifiedErrorId : Microsoft.SharePoint.Client.CollectionNotInitializedException,Microsoft.PowerShell.Commands.FormatDefaultCommand

When the script stops, if I go back and select the code and run Selection in PowerShell it will go ahead (sometimes) and create all the list and add them to the navigation.

I tried putting each line into a variable and calling it, also tried to put a start-sleep 15 between each library creation but it errors out still.

You can use Out-Null to remove the output from the pipeline:

Connect-PnPOnline -Url $NewSiteUrl -Credentials $cred

New-PnPList -Title Newsfeed -Template DiscussionBoard | Out-Null
New-PnPList -Title Tasks -Template Tasks | Out-Null
New-PnPList -Title Contacts -Template Contacts | Out-Null
New-PnPList -Title Calendar -Template Events | Out-Null
New-PnPList -Title Links -Template Links | Out-Null
Add-PnPNavigationNode -Title "Newsfeed" -Url "$NewSiteUrl/Lists/Newsfeed" -Location "QuickLaunch"
Add-PnPNavigationNode -Title "Tasks" -Url "$NewSiteUrl/Lists/Tasks" -Location "QuickLaunch"
Add-PnPNavigationNode -Title "Contacts" -Url "$NewSiteUrl/Lists/Contacts" -Location "QuickLaunch"
Add-PnPNavigationNode -Title "Calendar" -Url "$NewSiteUrl/Lists/Calendar" -Location "QuickLaunch"
Add-PnPNavigationNode -Title "Links" -Url "$NewSiteUrl/Lists/Links" -Location "QuickLaunch"
Add-PnPNavigationNode -Title "Manage Site Access" -Url "$NewSiteUrl/_layouts/groups.aspx" -Location "QuickLaunch"

Or put the lists in a csv file to loop through with if you have too many.

References:

format-default: the collection has not been initialized on Add-PnPFile after Apply-PnPProvisioning is Run.
