A SPD workflow has become suspended, but I'm unable to cancel it. I'm trying to kill the workflow with the PNP command, but thats not working either, Am I missing something?

I'm using:-

Stop-PnPWorkflowInstance -identity e31bd8e7-90f3-42a3-898b-e9ebd326befc -force -verbose

The response I get in powershell is

VERBOSE: Instance object not set. Looking up site workflows by GUID: e31bd8e7-90f3-42a3-898b-e9ebd326befc

The workflow is still stuck in suspended mode, I'm unable to kill it. Any suggestions?

  • did you try my edited reply ?

Here is a demo to stop workflow instance using PnP PowerShell. Get a running workflow instance and then stop it:

Connect-PnPOnline -url "https://tenant.sharepoint.com/sites/dev"

Get-PnPWorkflowInstance -List "DateTest" -ListItem 2 | Where-Object {($_.Id -eq "21870821-2e70-4c29-bca9-b07eef8e53b5")} |
        Foreach-Object {
            Stop-PnPWorkflowInstance -Identity $_ -Verbose -Force 

The Id in the code snippet above can be found in the workflow url:

  • I get this error message:- Stop-PnPWorkflowInstance : Cannot convert 'System.Object[]' to the type 'SharePointPnP.PowerShell.Commands.Base.PipeBinds.WorkflowInstancePipeBind' required by parameter 'Identity'. Specified method is not supported. At line:1 char:36 + Stop-PnPWorkflowInstance -identity $wfinstance + ~~~~~~~~~~~ + CategoryInfo : InvalidArgument: (:) [Stop-PnPWorkflowInstance], ParameterBindingException + FullyQualifiedErrorId : CannotConvertArgument,SharePointPnP.PowerShell.Commands.Workflows.StopWorkflowInstance

  • This could be because the Get-PNPWorkflowInstance returns multiple workflows that have already completed as well as the workflow that is suspended

  • @Akashic, If you have multiple started workflows in specific item, please use Foreach-Object to loop and get the specific workflow instance with Id

The Stop-PnPWorkflowInstance accepts -identity param as the workflow instance object. You can use Get-PnPWorkflowInstance command to get the instance and supply it to the stop workflow command.

  • Can you provide an example, this is just info from the documentation.
