I am having a few issues when a user tries to respond to a task using Lazy Approval. If they respond using Lazy Approval, the workflow fails and gives the following error:
Error in request approval action. Unauthorized attempt to update approval task by <domain name>\<userID>, The response has not been recorded. And the outcome shows 'Error.'
The user in question has appropriate permissions to approve the tasks, and if they approve / reject it using SharePoint interface it works fine. This happens only with Lazy Approval.
I am using Nintex Workflows for SP 2016, version 126.96.36.199
Could anyone please help me with this?
