I have created a segment within Customer Insights - Data that is a dynamic segment that updates daily, based off of a join of data from my Real-time Journeys Contact table, and some other internal data sources. This segment is targeting new users within the last 30 days of a specific attribute type, using an intersecting join.
When I attempt to use the segment in a Real-time Journey, I receive the following error, "Cannot read properties of null (reading 'map')" underneath the dropdown field in the Journey Builder, as well as "No Contactable Fields Found" within the dropdown itself.
The same email field (emailaddress1) that I use in Contacts for Segments within Real-time Journeys is present in the output of this data join, but Dynamics does not recognize it.
Can anyone assist?
