Return Type: Email Addresses semi-colon delimited coercion failure

Hi all!

I am trying to get email addresses for a list workflow and am receiving a Coercion Failure Message in the Set variable operation.

Workflow variables:

Email - string

currentOwners - Person or Group

I have Set: 'Email' equals Workflow Data currentOwners then I click the ... elipse to select Return Type. Return type of Email addresses, semi colon delimited throws the coercion error. I've tried making a emailBig variable that's multi lines of text in case length is an issue, but I get the same results.

Supporting Information: SharePoint/Nintex 2019.

List: System

Field: Owners - Person or Group - Multipeople allow, people only

List: UAT

Field: SystemId - number

The workflow runs on the UAT list and uses the foreign key systemId field to get the Owners from the System list and stores those in a Person or Group Nintex variable, currentOwners.

Any ideas what's up?

Thanks,

Erin
