An When I try to open Nintex Office 365 form, which is showing this Error

"An Error Occurred. Contact Your Site Administrator to update the app."

Root Cause of the Issue:

Google Chrome or browser is starting to implement more security controls in regards to third-party cookies, which is present in Incognito mode . They are beginning to block third-party cookies which Nintex Forms uses to communicate information between SharePoint Online and Nintex office 365 Forms - and Nintex form has blocked, Nintex Forms will not work correctly.

Unlock SharePoint NIntex Workflow Tasks With PowerShell

 

We had struggled with this task locking problem for a few months, once approver's completed task.  It seemed that the problem started after making updates from Microsoft and Nintex.  

It will display in the following message to edit workflow tasks

"This task is currently locked by a running workflow and cannot be edited."

After few hours research, I found out ways to unlock SharePoint Nintex workflow tasks using PowerShell script.

Solution:

[system.reflection.assembly]::LoadWithPartialName("Microsoft.SharePoint")

$siteUrl="http://TestSIte/"

$site=new-object Microsoft.SharePoint.SPSite($siteUrl)

$web=$site.OpenWeb()

$web.url

$i=0

write-host $web.lists

foreach($list in $web.lists){

    foreach($item in $list.items | where {$_[[Microsoft.SharePoint.SPBuiltInFieldId]::WorkFlowVersion] -ne 1}){

 

            if($item["Status"] -eq "Not Started")

            {

                  Try

                  {

                        Write-Host Unlocking workflow on $item.name

                        $item[[Microsoft.SharePoint.SPBuiltInFieldId]::WorkFlowVersion]=1;

                        $item.SystemUpdate()

                        $i++

                  }

                  Catch [System.Exception]

                  {

                        Write-Host Caught error trying to unlock workflow -ForegroundColor Red

                  }

            }

      }

}

Write-Host Unlocked $i workflows within $web.url

$web.dispose()

$site.dispose()
