I am trying to build an import scenario that creates external user accounts for all of our active accounts.
My desired outcome is below. The users email address is the login name and the user record is linked to the contact record.
When we use this in our external system, this is how we determine the customer that this user is associated to.

I made this scenario but I can’t get it to work. I am unable to get it to link to the contact linked entity. The mapping I am using is correct (ie: the string value for the display name matches the value in the linked entity box if I do it manually.
Here is the design of my scenario:

Here is the error I get when trying to processes this.

My assumption is I am mapping to the User Type and/or linked entity incorrectly. I am not all that familiar with import scenarios so I am hoping this is simple and obvious.
Any help would be appreciated! Thank you :)
