Hi everyone, I’ve been trying to complete the knowledge graph for module 5 but it’s telling me I need to create the Restaurant Promotions custom field (even though I did) and was able to add it to the Restaurant entity type. Maybe I’m doing something wrong but I’ve followed the instructions and tried it three times already 
Just figured it out! I didn’t set the custom validation to a max of 3 items
