Retrieving many to many relationship with additional Fields.

[AleksandrukTad]

Hey just have you came across situation that you have many to many relationship with additonal fields? This is my schema:

model Medicine {
  id                    Int      @default(autoincrement()) @id
  name                  String
}

model ActiveSubstance {
  id   Int    @default(autoincrement()) @id
  name String
}

model MedicineActiveSubstance {
  id                      Int             @default(autoincrement()) @id
  medicine                Medicine        @relation(fields: [medicineId], references: [id])
  medicineId              Int
  activeSubstance         ActiveSubstance @relation(fields: [activeSubstanceId], references: [id])
  activeSubstanceId       Int
  amountOfActiveSubstance Int
}

this is my nexus:

export const Medicine = objectType({
  name: 'Medicine',
  definition(t) {
    t.model.id()
    t.model.name()
  },
})

export const ActiveSubstance = objectType({
  name: 'ActiveSubstance',
  definition(t) {
    t.model.id()
    t.model.name()
  },
})

I can add t.model.medicineActiveSubstances (to activeSubstances) and t.model.medicineActiveSubstances (to medicines). But this causes an error when I try to add type to it:
"ERROR: No subset types are available. Please make sure that one of your GraphQL type is a subset of your t.model('')",

How do I retrieve medicine with all ActiveSubstances on it and amountOfActiveSubstance??

"ERROR: No subset types are available. Please make sure that one of your GraphQL type is a subset of your t.model('')", - This error appears because you name in Nexus model does not match prisma model. As soon as i matched them it works fine.
I hope this will help others that will come across this issue!
