Prisma Schema not updating properly after adding new fields

Question

As the title states, I am using Prisma 2 in a Next JS app. I have a very simple schema:

  model User {
  id             Int       @id @default(autoincrement())
  firstName      String
  middleName     String?
  firstLastname  String
  secondLastname String?
  email          String
  role           String
  group          Group?    @relation(fields: [groupId], references: [id])
  groupId        Int?
  activity       Activity? @relation(fields: [activityId], references: [id])
  activityId     Int?
  createdOn      DateTime  @default(now())
  updatedOn      DateTime  @default(now())
}

model JobTitle {
  id        Int      @id @default(autoincrement())
  name      String
  createdOn DateTime @default(now())
  updatedOn DateTime @default(now())
}

model Group {
  id        Int      @id @default(autoincrement())
  name      String
  users     User[]
  createdOn DateTime @default(now())
  updatedOn DateTime @default(now())
}

model Activity {
  id    Int    @id @default(autoincrement())
  name  String
  users User[]
}

I added the email field on the User model and changed the groupId and activityId fields to be optional. I also changed the type for the role field to String. I run prisma migrate and prisma up to create a new migration and sync the database (using a remote heroku postgresql database as my datasource) and everything runs fine. No errors. However, when I try to create a new User, I get the following error:

An error ocurred:  PrismaClientValidationError:
Invalid `prisma.user.create()` invocation:

{
  data: {
    firstName: 'John',
    middleName: 'Edgar',
    firstLastname: 'Doe',
    secondLastname: 'Smith',
    email: '[email protected]',
    ~~~~~
    role: 'ADMIN',
          ~~~~~~~
+   group: {
+     create?: GroupCreateWithoutUsersInput,
+     connect?: GroupWhereUniqueInput,
+     connectOrCreate?: GroupCreateOrConnectWithoutusersInput
+   },
+   activity: {
+     create?: ActivityCreateWithoutUsersInput,
+     connect?: ActivityWhereUniqueInput,
+     connectOrCreate?: ActivityCreateOrConnectWithoutusersInput
+   },
?   createdOn?: DateTime,
?   updatedOn?: DateTime
  }
}

Unknown arg `email` in data.email for type UserCreateInput. Did you mean `role`?
Argument role: Got invalid value 'ADMIN' on prisma.createOneUser. Provided String, expected RoleCreateOneWithoutUserInput:
type RoleCreateOneWithoutUserInput {
  create?: RoleCreateWithoutUserInput
  connect?: RoleWhereUniqueInput
  connectOrCreate?: RoleCreateOrConnectWithoutUserInput
}
Argument group for data.group is missing.
Argument activity for data.activity is missing.

Note: Lines with + are required, lines with ? are optional.

It seems like the operation is using a previous version of the schema seeing as how it says that the email field does not exist and the role field is not a String type. Also, the groupId and activityId fields are still shown as required. I don't know if there some sort of cache. I already tried deleting all migrations and redeploying everything from scratch. I even deleted the database in heroku and started fresh but I am still getting the same error.

Answer 1

Running an npm install (no need to remove node_modules) and then re generating the Prisma types can fix this issue.

Since npm i removes the old Prisma generations, npx prisma generate will have to generate new ones from your schema.prisma.

Ryan's comment about adding a post install script for Prisma is a nice QOL improvement, too.

Edit: Closing and opening your editor (in my case VsCode) will fix the red line errors. I think the extension struggles to update itself with the new changes. It's a pain but does work if the other solutions don't.

Answer 2

I had something closer to this problem. In my case, I updated my Schema.prisma with new models but anytime I run "prisma migrate dev", it wouldn't update. It turns out the error was because I didn't hit "Save" after making the changes before running the code. (In my defence, I thought auto-save took care of that but no).

Try saving the file again before you run "prisma migrate dev".
