I have many state machine workflows running on my Site collection. All of them are having flexi task creation action for getting approvals. Now a days users started to receive error messages saying "No item exists at http://url/Lists/Workflow Tasks/EditForm.aspx?ID=3144", when they click on the approval link in the email. It happens only when the user tries to click on the email as soon as the email is received. If they click on it after few minutes then they are able to approve it without any error.
Can any of you help me on this. I searched with the correlation id and i was unable to find anything more than this No item exists error message.
It happens only to task form which is edited using nintex forms. If it's not edited then there's no issue. Also it takes approximately 1 minutes to load properly.
