Hello all,


On a on prem 2013 environment, I have backed up and restored a site collection containing Nintex Workflows.

Now I'm checking the workflows on the restored site collection and have to change a groupname in the Set Item Permission action.

It can find the groups, using the picker function but when I save the action it shows any attention mark. Hoovering the action, it shows the message:

Error validating configuration

  • An item with the same key has already been added.


I've already deleted the permission rows in the action, leaving one and then it saves correct

When I add a second or third permission, the attention mark shows and removing the last added permission doesn't solve the problem. Even with only the first added permission, the attention mark stays.

It doesn't seem to happen on Current Item, but only on items within another library.


I've also removed the entire action, published the workflow and added the action back in, but htat only worked once.


Any idea what causes this issue and how to solve it?


Thanks in advance for your support!
