Invalid index in type

[navalex]

Hello,

I'm trying to use your module to progamaticly generate JSON Schema from my defined types. Most of my custom types extends from packages types, such as Prisma. I don't have a lot of types, for here there are:

import { Prisma, Challenge } from "@prisma/client"
import { SessionRequest } from "supertokens-node/framework/fastify"
import { Certificate } from "tls"

export interface ChallengeWithStats extends Challenge {
	currentValue: number
}

export interface ExoCertificate extends Certificate {
	DC: string
}

interface RouteInterface {
	Params?: unknown
	Body?: unknown
}

export interface FastifyRequestSession<T extends RouteInterface> extends SessionRequest {
	body: T["Body"]
	params: T["Params"]
}

export interface UserWithRoles extends Prisma.UserGetPayload<{ include: { preferences: true } }>{
	roles: string[]
}

export interface SessionJsonData {
	sessionId: string
	start_date: Date
	end_date: Date
	steps: number
	distance: number
	verticalDuration: number
	walkDuration: number
	totalDuration: number
}

export interface SessionStatistics {
	total: {
		steps: number
		distance: number
		verticalDuration: number
		walkDuration: number
		totalDuration: number
	}
}

Note that all those types are located in ./src/types/**.ts, and all exported in ./src/types/index.ts.

Here is my script I'm trying to run to make my schema:

const fs = require("fs")

import("ts-json-schema-generator").then(async tsj => {
	const config = {
		path: "./src/types/index.ts",
		tsconfig: "./tsconfig.json",
		type: "*",
	}

	const outputPath = "./testSchema.json"

	const schema = tsj.createGenerator(config).createSchema(config.type)
	const schemaString = JSON.stringify(schema, null, 2)
	fs.writeFile(outputPath, schemaString, err => {
		if (err) throw err
	})
})

This file is located in ./src/generateSchema.js and i'm running the script like node ./src/schemaGenerator.js

And the output throw me this error:

file:///src/api/node_modules/ts-json-schema-generator/dist/src/NodeParser/IndexedAccessTypeNodeParser.js:60
                    throw new LogicError(`Invalid index "${type.getValue()}" in type "${objectType.getId()}"`);

Node.js v20.13.1

And to be honest, I have no clue about how to read and correct this at this point!

Do you guys have any clue on how to fix this ?

Thanks

[domoritz]

Thanks for the report. Can you provide a minimal reproducible example that demonstrates the issue?

[navalex]

Yeah sorry, here is a little project I made up to reproduce this:

package.json

{
  "name": "test",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "description": "",
  "devDependencies": {
    "@types/node": "^20.12.12",
    "prisma": "^5.14.0",
    "ts-json-schema-generator": "^2.2.0",
    "ts-node": "^10.9.2",
    "typescript": "^5.4.5"
  },
  "dependencies": {
    "@prisma/client": "^5.14.0"
  }
}

prisma/schema.prisma

generator client {
    provider = "prisma-client-js"
}

datasource db {
    provider = "sqlite"
    url      = env("DATABASE_URL")
}

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

types/index.ts

import { User } from '@prisma/client';

export interface UserTest extends User {
    newField: string;
}

schemaGenerator.js

const fs = require("fs")

import("ts-json-schema-generator").then(async tsj => {
	const config = {
		path: "./types/user.ts",
		tsconfig: "./tsconfig.json",
		type: "*",
		schemaId: "WdcTypes",
	}

	const outputPath = "./schemas"

	const schema = tsj.createGenerator(config).createSchema(config.type)
	const schemaString = JSON.stringify(schema, null, 2)
	fs.writeFile(outputPath, schemaString, err => {
		if (err) throw err
	})
})

This example + my personnal tests seems to show that any import from the @prisma/client seems to make the generator crash.

[domoritz]

That's not yet minimal if you can remove anything and the error state does not change. Oncer you identify the offending change, you can see how it's causing the issues you see.

[navalex]

Okay,

I edited my schema:

generator client {
    provider = "prisma-client-js"
}

datasource db {
    provider = "sqlite"
    url      = env("DATABASE_URL")
}

model User {
    name String @unique
}

That make all my files as minimal as possible (not that the error also trigger with the CLI, without using my .js file).
The error occur when I extends any Prisma type. The moment I remove Prisma imports, everything works, if I add a Prisma type, it triggers this error

[arthurfiorette]

This might be fixed by #1924

[arthurfiorette]

#343 could also help here

[arthurfiorette]

@navalex can you try with v2.3.0-next.2?

After #1963 added diagnostics, the error thrown will have more info about it.

[arthurfiorette]

Probably duplicate of #542

[navalex]

@navalex can you try with v2.3.0-next.2?

After #1963 added diagnostics, the error thrown will have more info about it.

Okay so, after testing, it does fix the issue on my basic exemple, but does not on my main project. I tried both 2.2.0-next.0 and 2.3.0-next.2, the last one give an enormous output that seems to dump both a ts-json-schema-generator file and probably my file that throw the error (the Prisma generated client, so a big one).

I don't know if I'll have enough time to do more tests this week, so here is at least the output error, may give you more infos:

[arthurfiorette]

Hey @navalex what about our latest release?

[imjuni]

@arthurfiorette hello, thank you for your effort.

I create reproducible repository: https://github.com/imjuni/reproducible-prisma

sadly, ts-json-schema-generator cannot generate schema from mapped access type using prisma generated, like: https://github.com/imjuni/reproducible-prisma/blob/e2590cf2dff10f0d1eb7ad887a82656be6489faf/src/dto/ITagDto.ts#L6

I was tested 2.3.0-next.5 and 2.4.0-next.1.

[imjuni]

Is there any progress on this issue? I tested it with the latest released version 2.4.0, but the same error still occurs.
