I am using postgres with Prisma in my nodejs project.

I have a prisma model with the below schema

model ParentObject {
  parent_object_iid        String           @id @default(dbgenerated("gen_random_uuid()")) @db.Uuid
  ChildObjects ChildObject[]
  SiblingObjects SiblingObject[]
} 

When I execute

parentAccount = await prisma.parentAccount.create({ data: {} });
or 
parentAccount = await prisma.parentAccount.create({});

I expect an empty record created with a unique random UUID generated and returned. But this does not create any new record but returns the first record in the table.

Is there a different method I need to be using like await prisma.parentAccount.createRecordWithNoData()

It works if the schema is

model ParentObject {
  parent_object_iid        String           @id @default(dbgenerated("gen_random_uuid()")) @db.Uuid
  ChildObjects ChildObject[]
  SiblingObjects SiblingObject[]
  name string
} 

and executing

parentAccount = await prisma.parentAccount.create({ data: {name: 'john doe'} });
