Prisma.JsonValue occurs Maximum call stack size exceeded

Bug Report

Summary

When there is a Prisma.JsonValue type in the User model of Prisma, an error occurs.

Actual behavior: error occurred

Maximum call stack size exceeded - src/app.controller.ts.8:49.

// schema.prisma

model User {
  id    Int     @id @default(autoincrement())
  email String  @unique
  name  String?

  // here
  content Json?
  posts Post[]
}

model Post {
  id        Int     @id @default(autoincrement())
  title     String
  content   String?
  published Boolean @default(false)
  author    User    @relation(fields: [authorId], references: [id])
  authorId  Int
}

// app.contoller.ts

@Controller('/')
export class AppController {
  /**
   * Maximum call stack size exceeded
   */
  @TypedRoute.Get()
  callStackExceeded(): User[] {
    return [];
  }

  /**
   * Ok
   */
  @TypedRoute.Get()
  noProblem(): Post[] {
    return [];
  }
}

If I comment out callStackExceeded, no error occurs.

  export type JsonObject = {[Key in string]?: JsonValue}

  /**
   * From https://github.com/sindresorhus/type-fest/
   * Matches a JSON array.
   */
  export interface JsonArray extends Array<JsonValue> {}

  /**
   * From https://github.com/sindresorhus/type-fest/
   * Matches any valid JSON value.
   */
  export type JsonValue = string | number | boolean | JsonObject | JsonArray | null

Here is the Prisma.JsonValue type.

Just ran into this today

[samchon]

@dohyuu Due to type JsonValue = ... | JsonValue[] declaration, analyzing is not possible.

What about just using any type in that case?

[samchon]

@DavidVaness This issue needs entire refactoring in typia. I'll do this. Thanks

[dohyuu]

@samchon I solved the problem with a prisma interface generator that was customized for me. (Prisma.JsonValue is also replaced with any.)

Thank you for your answer.

@dohyuu @DavidVaness

Building and publishing next version of nestia.

After a day, upgrade to @nestia/core@1.3.0 and @nestia/sdk@1.3.0, then everything would be fine.

[DavidVaness]

Thank you @samchon
Will report back on Monday

[DavidVaness]

@samchon I have updated to the latest typia + nestia and the issue persists. Only way is to remap the Prisma.JsonValue to any or some other type.

Seems like its not fixed

[samchon]

@DavidVaness Tested your code, but there's not any problem.

Which version are you using?

If same error being repeated, can you provide me a reproducable repo?
