1 to 1 relations get @unique applied.

I am having an issue with Prisma 1 to 1 relationships, prisma formats my relation with @unique which creates a unique constraint on the column. This makes it to where the field can only have 1 null in it. The opposite table is optional, I have set the relation with ? on them so that it reflects, but this @unique getting added prevents the data from saving after the first record is added to the system.

model Intake {
   legalCase    LegalCase?         @relation("LegalCase_intake")
}

model LegalCase {  
  ...
  intakeId     String?         
  intake       Intake?         @relation(name: "LegalCase_intake", fields: [intakeId], references: [id])

After I run prisma apply the intakeId looks like this …

intakeId     String?         @unique
intake       Intake?         @relation(name: "LegalCase_intake", fields: [intakeId], references: [id])

legalCase: input.legalCase != null ? {} : undefined I ended up patching my prisma call to check if the legal case is included in the call, and if not, dont send it through.
