I've created a flow for attendees of training classes that takes a csv containing member id's (scanned upon entry to class), and creates a record collection variable with them. I have a get attendee records that looks up all attendee records (may have registered but not attended) for the current training class product (from screen flow). I'm trying to use Collection Filter on the get attendee records collection by doing a loop on the scanned record collection (for those that actually attended), and then assign a single attendee record variable using the currentItem_Filter.Id value from the Collection Filter, then adding that to a Record Collection variable to update at the end. The flow fails, showing the Id as null. However, when looking at the failed flow interview, the Id shows in the Collection Filter, but for some reason it doesn't seem to pass thru with the currentItem_Filter.Id value. Has anyone had any experience with Collection Filters and know where I may be going wrong? See screenshots. #Flow
