    It would resolve you problem

    ${userType?keep_before_last("|")}

    I may create an issue if a user does not have any role but I think every user will have at least one role.  Right?

    Here is an updated version.  Here is the output https://prnt.sc/jsccwr

     <#assign userTypeCount = 0>
<#assign userType = ""/>
  <#list restadmin("/users/id/${user.id}/roles").roles.role as role>
    <#assign userType += role.name >
    <#assign userTypeCount ++>
 
    <#-- only add separator if user has more than one role -->
      <#assign userType += ' | '>
  </#list>
${userType}
${userType?keep_before_last("|")}

VikasB thanks for the reply.  I am defining the var already. I just left that piece of code out of my snippet above. 

Currently what I am getting displayed for user with one role is: 
"Contributor |" 

If  they have two or more roles I get :
"Administrator | Contributor |"

 

My desired output for one role is 
"Contributor"

and for two would be:
"Administrator | Contributor "


I've played around with a few variations of my condition, with similar results. I can't quite figure out what is going on as this is fairly simple logic.
