I have a junction called MeetingContactRelation to link attendees to a meeting:
Meeting - MeetingContactRelation - Contact
I have a hidden rich text field on Meeting and want to store the concatenated list of Contacts' names in it, so I can merge it into a Lightning template.
The idea is when Meeting is saved, Process Builder calls a flow which iterates over all the MeetingContactRelations. For each relation it will look up the name of the related contact and Add it via a concatenation formula to the merge field.
I get this error.
The flow failed to access the value for MeetingContactRelation.Contact__r.Name because it hasn’t been set or assigned.
