Get display names from a Person and Group column in a custom workflow task

Not sure about Groups, but I'm sure it can be done.  Here is how I do it for an individual person.  Create a workflow variable and make it a single line of text.   Set the value of the variable with this setting:

In your circumstance, your source will most likely be your variable you used for query item.  My source is the list item.  Hope this helps.  

Hello @kunalpatel 

I did the above but the workflow keeps failing.

Coercion Failed: Unable to transform the input lookup data into the requested type.

@Rudixx can you share the configuration screenshot too? Also, is this one value or multiple values?

@kunalpatel 

Sure, this is the configuration from my last try, which errors too.

There can be 0 values or more than 1.

On a parent site, I have a list of departments with columns, Manager (multi person or group column) and Supervisors (multi person or group column).

On a child site I am looking up the above values.

This is my workflow:

1. Query List and save managers and supervisors in two separate collection variables.

2. For Each action, I am storing the values from COL_Supervisors in POG_Supervisors which is people or group variable. I've tried other types too with no luck.

3. Run if action to run only if the POG_Supervisors variable is not empty.

4. Regular Expression to remove domain prefix from the logins, pattern: i:0#.w|[a-z]{3}-dc\

5. Set variable, saving POG_Supervisors - Display Names, Semicolon Delimited in single line of text variable SLOT_Supervisors

6. Error

I managed the get the names and I described my steps in this thread: https://community.nintex.com/t5/Nintex-for-SharePoint-Forum/Get-Display-Names-from-another-site-list-s-multi-person-column/m-p/209427/highlight/true#M79227

Please feel free to take a look and let me know if it could be simplified.
