Error: Cannot set the key "logTrace". No CLS context available, please make sure that a ClsMiddleware/Guard/Interceptor has set up the context, or wrap any calls that depend on CLS with "ClsService#run"

I'll have a look. But it might be related to this one: https://github.com/Papooch/nestjs-cls/issues/49

Okay, so after looking into it, I found the error. In your tests, you never bound the ClsMiddleware - it is only bound in your main.ts, which is not used in the test.

I see you're binding the AuthenticationMiddleware in your AppModule, so I removed the ClsMiddleware registration out from main and added it to your AppModule before the AuthenticationMiddleware like so:

export class AppModule implements NestModule {
  configure(consumer: MiddlewareConsumer) {
    consumer.apply(ClsMiddleware).forRoutes('(.*)');
    consumer.apply(AuthenticationMiddleware).exclude('/').forRoutes('(.*)');
  }
}

Now the test passes as expected.
