Connect-PnpOnline not working for access token

Question

I am facing issue while connecting to SharePoint online using Access token -

$accessToken = <Generated using 'Client Secret' & 'Client Id' , Rest query returns access token>

Connect-PnPOnline -AccessToken $accessToken -Url $SiteURL -ReturnConnection

It seems some versioning conflict please help as it was taking long time to troubleshoot.

Issue:

Get-PnPList : Cannot convert 'System.Object[]' to the type 
'PnP.PowerShell.Commands.Base.PnPConnection' required by parameter 
'Connection'. Specified method is not supported.

Hi @Amol Khairnar

Judging from the error message you provided, the place where the error is reported is:

• ... cList = Get-PnPList -Identity $libTitle -Connection $SiteConn -Includ ...

Cannot convert 'System.Object[]' to the type 'PnP.PowerShell.Commands.Base.PnPConnection' required by parameter 'Connection'. Specified method is not supported.

The cause of the error is: you are passing an array of connections instead of a single connection to the -Connection parameter of Get-PnPList.

You can check the type of the $SiteConn variable with Get-Type $SiteConn and make sure it is a PnP.PowerShell.Commands.Base.PnPConnection object, not a System.Object[] array.

You could also try using the -Web parameter instead of the -Connection parameter to specify the Web where the list is located.
