When performing a create operation, data is the type of XOR<ApplicationCreateInput,ApplicationUncheckedCreateInput > which means you can either provide ApplicationCreateInput which will have all nested relations specified or you can directly provide the ID as in the case of applicantId field but you can’t mix them. So you will need to use the fields specified in ApplicationUncheckedCreateInput in order to create it. Also, Unchecked input types allow you to perform some operations that Prisma considers dangerous like directly writing foreign keys. Prisma allows you to choose either a safe or an unchecked input type when doing operations like create. In this case, Prisma wants you to perform the create action using the Unchecked input type.
