Can anyone help me with this problem? I am sure [Candidate Index] has been set as Key column, but it still pop up with this issue.
@Hong_Yaw_Kuang I don’t know the details of your use case, but the error message is saying that you’re using a single value where a list is expected.
LIST([Candidate Index]) will get rid of the error, but I’m not sure if it’s going to do what you expect.
Still the same error message, I wonder is this a bugs?
