Any idea on how to fix the issue? Thank you in advance i have been stuck with this issue since 3 days now :(

Side note: The error appeared once I upgraded my node version to 19.x

[ElMehdiBouamama]

Is this issue related to the one I have?
#701

I am still trying to figure out how to fix this issue. Please if anyone can help I would be more than grateful!

[ElMehdiBouamama]

Is this repository still maintained?

[Brooooooklyn]

@ElMehdiBouamama you should provide a minimal reproducible repo for your issue so that I can debug it

[ruscon]

Got the same issue.
@Brooooooklyn could you help.

tsconfig.json

  "compilerOptions": {

    "target": "ESNext",

    "experimentalDecorators": true,
    "esModuleInterop": true
  }
}

Small example to reproduce:

src/server.ts

import { Module } from '@nestjs/common';

@Module({})
export class AppModule {}

run

SWCRC=true SWC_NODE_PROJECT=./tsconfig.json node --import @swc-node/register/esm-register ./src/server.ts
