I'm working through a tutorial, and cannot get things to post to Prisma from GraphQL, because when I look at my Prisma, I'm pushing two "ghost" fields that are not in my datamodel.graphql file but are being sent to Prisma anyway, and are of a data type that I cannot post with GraphQL, but are required, thus making nothing going to Prisma of this type succeed. How can I make these fields not create in this type?
