SharePoint Online - PnP PowerShell - Remove Installed Apps

Question

Hi MS Q&A,

Have been attempting to report on available Apps deployed / installed against a SharePoint Online Site Collections via the following PowerShell operations to help with subsequent removal / uninstall:

$web = Get-PnPWeb –Includes AppTiles
$appTiles = $web.AppTiles | ? { $_.AppType -eq "Instance" }  

The main intention was attempting to locate instances of following Apps and conduct removal:

1. Nintex Workflow for Office 365
2. Nintex Forms for Office 365

Unfortunately, have been unsuccessful with attempts with App removal via Remove-PnPApp and Uninstall-PnPApp cmdlet against the App ID obtained from the prior AppTiles object review attempt.

The following was the encountered error message against each above cmdlet attempted:

{"odata.error":{"code":"-1, Microsoft.SharePoint.Client.ResourceNotFoundException","message":{"lang":"en-US","value":"Exception of type 'Microsoft.SharePoint.Client.ResourceNotFoundException' was thrown."}}}

Seeking any advice if there are any alternative ways to remove the App via PnP PowerShell.

Appreciate any advice and information.

Thank you.

Hi @Daniel Chee

Per my research, there is no such pnp powershell cmdlet to delete Nintex Workflow for Office 365. And I feel regretful to inform you that it turns out to be a by-design one. For Nintex Workflow, I will recommend you to raise a new ticket in Nintex Community. This is a dedicated forum to discuss issues about Nintex Workflow. You might get some more professional advice there.

I was able to get this working, not with PMP, but with CSOM. The site https://clavinfernandes.wordpress.com/2022/08/16/remove-app-instances-from-a-sharepoint-site-using-powershell/ provided a good starting point for the solution.

From Clavin's solution, I was able to extract the ProductID's for the 2 Nintex apps (353e0dc9-57f5-40da-ae3f-380cd5385ab9,5d3d5c89-3c4c-4b46-ac2c-86095ea300c7). Then using the call $Ctx.Web.GetAppInstancesByProductId($productId), I was able to find the apps within each site and successfully perform the removal.

#Setup Credentials to connect

$Cred = Get-Credential

$SiteURL = "<Sharepoint Site>"

$Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)

$Ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.UserName,$Cred.Password)

$productIDs = "353e0dc9-57f5-40da-ae3f-380cd5385ab9","5d3d5c89-3c4c-4b46-ac2c-86095ea300c7"

foreach ($productID in $productIDs) {

$App = $Ctx.Web.GetAppInstancesByProductId($productId)

$Ctx.Load($App)

$Ctx.ExecuteQuery()

if ($app.count -eq 1) {

#Uninstall App Instance

write-host "trying to remove: " $app.title

Try {

$App.Uninstall()

$Ctx.ExecuteQuery()

}

Catch {

write-host -f Red "Error:" $_.Exception.Message

}

} else {

write-host "Not found " $productID

}

}
