Actioned Tasks Not Leaving User Worklist

Can you show me how your task is configured in the designer? Specifically the section that I've attached a screenshot of

Here is the picture requested.

Also, on further troubleshooting I discovered that actioning of the tasks works perfectly on the development environment, but not on the production environment. i.e. this issue I am currently having doesn't happen on the development server.

Here is what I have under the options, there is nothing unusual there.

So its confirmed that its an environment issue, so you can log a support ticket to Nintex portal, they should help you out and in the meantime, Could you please check if the user details are synced correctly in Identity.Identity table in K2 DB.

SO I reached out to the K2 Engineer via the customer support.

According to the engineer, the issue happens to be a bug in the system, which creates whitespaces after the last character in the username when the usernames are been created.

So with this development, the workflow username is different from the main username.

This script was ran on the DB to check instances of users with the issue:

SELECT *, '[' + [ActionerName] + ']'
FROM [Server].[Actioner]
WHERE [ActionerName] LIKE '% %'

After which another script was ran to update the usernames, and close out the whitespaces. Here is the script below:

Update [Server].[Actioner]
Set [ActionerName] = LTRIM(RTRIM([ActionerName]))
WHERE [ActionerName] LIKE '% %'

After running this two script, users were able to successfully action tasks, and it left there tasklists.
