Describe the bug

I had this bug when try to update the version.

Node version used: v20.9.0

I tried installing the package with pnpm, npm and yarn. With yarn I get a node version error... and the others I get the error above when execute the command.

Reproduction repo

No response

Yep. Same here. SyntaxError: Unexpected token } in JSON at position 497.

Hey both of you! 👋🏻

Is it possible to share the repository where you try to run the command?

[samuel-s-marques]

Hey! I'm trying to run on thisdatedoesnotexist-server. It's still using AdonisJS v5. I'm trying to update it to v6.

[Julien-R44]

sorry I missed that issue. i will take a look

[Julien-R44]

@samuel-s-marques can you give more information? I just tried to run upgrade-kit on your repo and it seems to works fine. Can you give your node version and also the command/patch you ran?

I'm using Node 21.6

I had the same problem and found this code in upgrade-kit/src/runner.ts

loader.update('Loading config files')
    this.#patchers = this.#options.patchers.map((factory) => factory(this))
    this.rcFile = new RcFile(join(this.#options.projectPath, '.adonisrc.json'))
    this.tsConfigFile = new Tsconfig(join(this.#options.projectPath, 'tsconfig.json'))
    this.pkgJsonFile = new PkgJson(join(this.#options.projectPath, 'package.json'))

For me the problem was that in my tsconfig.json a line was commeted out:

{
    "extends": "adonis-preset-ts/tsconfig.json",
    "include": ["**/*"],
    "exclude": ["node_modules", "build"],
    "compilerOptions": {
        "outDir": "build",
        "rootDir": "./",
        "sourceMap": true,
        "paths": {
            "App/*": ["./app/*"],
            "Config/*": ["./config/*"],
            "Contracts/*": ["./contracts/*"],
            "Database/*": ["./database/*"]
            // "@ioc:/*": ["./contracts/*"]  <------ remove this line
        },
        "types": [
            "@adonisjs/core",
            "@adonisjs/repl",
            "@japa/preset-adonis/build/adonis-typings",
            "@adonisjs/lucid",
            "@adonisjs/auth",
            "adonis5-jwt",
            "@adonisjs/session",
            "@adonisjs/mail",
            "@adonisjs/drive-s3"
        ]
    }
}

There are multiple .json configs so it could be that you need to check the other config files as well (.adonisrc.json, tsconfig.json, package.json).

This fixed the error for me. I also had another error message but it resolved after I upgraded to node v21.

Same problem here.

@royvanderzon's solution didn't work. I had no comments in any of my json files.

[Julien-R44]

i need a repro or at least more informations. otherwise there's nothing I can do to help

I had a similar issue and it wasn't a comment that was causing the problem, but the last element of an object in my tsconfig.json had a comma (,)...so it was expecting a new line. VSCode wasn't complaining so it went unnoticed.
