Prisma zod enum validation

I have this prisma schema:

enum RealEstateType {
  house
  apartment
  office
  garage
  land
  store
  industry
  other
}
...
model RealEstate {
  id            Int                 @id @default(autoincrement())
  status        RealEstateStatus
  title         String
  description   String
  availableFrom DateTime
  createdAt     DateTime            @default(now())
  updatedAt     DateTime            @updatedAt
  userId        String
  user          UserData            @relation(fields: [userId], references: [userId])
  type          RealEstateType
  contactId     String?
  contact       UserData?           @relation(name: "RealEstateContact", fields: [contactId], references: [userId])
  favorites     Favorite[]
  Message       Message[]
  documents     Document[]
  energy        EnergyEfficiency[]
  location      RealEstateLocation?
  features      RealEstateFeatures?
  pricing       RealEstatePricing?

  @@index([userId])
  @@index([contactId])
}

enum RealEstateType {
  house
  apartment
  office
  garage
  land
  store
  industry
  other
}
...
model RealEstate {
  id            Int                 @id @default(autoincrement())
  status        RealEstateStatus
  title         String
  description   String
  availableFrom DateTime
  createdAt     DateTime            @default(now())
  updatedAt     DateTime            @updatedAt
  userId        String
  user          UserData            @relation(fields: [userId], references: [userId])
  type          RealEstateType
  contactId     String?
  contact       UserData?           @relation(name: "RealEstateContact", fields: [contactId], references: [userId])
  favorites     Favorite[]
  Message       Message[]
  documents     Document[]
  energy        EnergyEfficiency[]
  location      RealEstateLocation?
  features      RealEstateFeatures?
  pricing       RealEstatePricing?

  @@index([userId])
  @@index([contactId])
}

And this zod validation:

const apartmentTypes = [
    'house',
    'apartment',
    'office',
    'garage',
    'land',
    'store',
    'industry',
    'other'
] as const;

export const createRealEstateSchema = z.object({
    type: z.enum(apartmentTypes),
    title: z.string().min(3).max(30),
    description: z.string().min(3).max(30),
    availableFrom: z.date(),
    contactId: z.string().optional(),
    location: locationSchema.optional(),
    features: featuresSchema.optional(),
    pricing: pricingSchema.optional(),
    documents: z.array(createDocumentSchema),
});

const apartmentTypes = [
    'house',
    'apartment',
    'office',
    'garage',
    'land',
    'store',
    'industry',
    'other'
] as const;

export const createRealEstateSchema = z.object({
    type: z.enum(apartmentTypes),
    title: z.string().min(3).max(30),
    description: z.string().min(3).max(30),
    availableFrom: z.date(),
    contactId: z.string().optional(),
    location: locationSchema.optional(),
    features: featuresSchema.optional(),
    pricing: pricingSchema.optional(),
    documents: z.array(createDocumentSchema),
});

This is my create route:

export const realEstateRouter = router({
    create: protectedProcedure
        .input(createRealEstateSchema)
        .mutation(async ({ ctx, input }) => {
            const userId = ctx.auth.userId;
...
            const newRealEstate = await ctx.prisma.realEstate.create({
                data: {
                    ...rest,
                    type: rest.type as unknown as RealEstateType,
                    status: RealEstateStatus.PENDING,
                    user: {
                        connect: {
                            userId: userId,
                        }
                    },
                    contactId: undefined,
                    location: {
                        create: newLocation,
                    },
                    features: {
                        create: newFeatures,
                    },
                    pricing: {
                        create: newPricing,
                    },
                },
            });
...

export const realEstateRouter = router({
    create: protectedProcedure
        .input(createRealEstateSchema)
        .mutation(async ({ ctx, input }) => {
            const userId = ctx.auth.userId;
...
            const newRealEstate = await ctx.prisma.realEstate.create({
                data: {
                    ...rest,
                    type: rest.type as unknown as RealEstateType,
                    status: RealEstateStatus.PENDING,
                    user: {
                        connect: {
                            userId: userId,
                        }
                    },
                    contactId: undefined,
                    location: {
                        create: newLocation,
                    },
                    features: {
                        create: newFeatures,
                    },
                    pricing: {
                        create: newPricing,
                    },
                },
            });
...

But I get this error

Argument type: Got invalid value 'apartment' on prisma.createOneRealEstate. Provided String, expected RealEstateTypeCreateNestedOneWithoutRealEstatesInput:
type RealEstateTypeCreateNestedOneWithoutRealEstatesInput {
  create?: RealEstateTypeCreateWithoutRealEstatesInput | RealEstateTypeUncheckedCreateWithoutRealEstatesInput
  connectOrCreate?: RealEstateTypeCreateOrConnectWithoutRealEstatesInput
  connect?: RealEstateTypeWhereUniqueInput
}

}

How can I properly use the enum type?

Have you tried z.nativeEnum()?
