I am trying to auto assign issues based off the department and class that is associated with the issue.
I am using a lookup table by having Department and Class be the key then having account Id be the value.

Then I create a variable that holds the Key to the lookup Table.

Finally I use the key to get the person I want to assign the issue to

The issue is that for some reason it says specified user does not exist or you do not have required permissions. When I log it shows the Key as Hardware_Air Power and for the value I have tried accountID, email, and username.
Any help with this issue is greatly appreciated!
