Graphql schema generation fails when using @TypeGraphQL.omit() on Int field

[luca-rath]

Describe the Bug

If a prisma model contains only one single Int field which is omitted using /// @TypeGraphQL.omit(output: true, input: true), the following error occurs when generating the graphql schema:

To Reproduce

I have created a pull request in my fork of this repository to reproduce the bug, see luca-rath#1

Expected Behavior

There should be no error

Environment (please complete the following information):

• OS: macOS Monterey 12.2
• Node 14.19.0
• typegraphql-prisma version 0.18.4
• Prisma version 3.8.1
• TypeScript version 4.5.5

Model with no fields 🤔 Interesting...

[luca-rath]

Sorry, I expressed myself wrong ... The model contains multiple fields with types other than Int and only one single field with type Int, which is omitted using the comment

[luca-rath]

This is the schema for the Post model:

model Post {
  id        String   @default(cuid()) @id
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
  published Boolean
  title     String
  content   String?
  author    User?    @relation(fields: [authorId], references: [id])
  authorId  String?
  /// @TypeGraphQL.omit(output: true, input: true)
  foo       Int      @default(1)
}

This is related to #19.

I think I need to find a way to do not emit those types and related fields somehow, as Prisma fix won't apply to the case of omitting the last field.

any update?

i reproduce this error today, the only workarround i see is change the type to other than Int
