koa.js returning 404 "Not Found" after signup, instead of the token from ctx.body

Question

I'm failing to return my token to actually be retrieved from my middlewares using xhr agents say supertest and postman. after I signup my user.

I'm trying to get the jwt from body so i can make authenticated requests, but for some reason i keep on getting "Not Found".

Please take a look at my code..

signup route

router.post('/signup', signUp);    

What important about /signup route, is if I add a middleware after signUp I can access the ctx.response.body passed from signUp middleware but I can't publish it anyware. Or i don't know how.

and the signUp middleware

const signUp = async (ctx, next) => {
    
    const bodyInfo = await ctx.request.body;

    if(!bodyInfo.username || !bodyInfo.password) {
        ctx.status = 402;
        ctx.body = "Error, username and password must be provided!";
    }

    const userInst = new User(bodyInfo);

    userInst.save(async(err, user) => {
        
        if(err) { return next(err); }

        const token = tokenForUser(user);

        ctx.body = token;

        return next();
    });
};

export { signUp, signIn };

I should mention that this saved the data fine and when I check in the database the data is there, console.logs of ctx.response.body in a next middleware to signUp shows the generated token too.

I test /signup with this code:

beforeEach(async () => {
    a_user = { "username": "testing",
           "password": 'newpassword',
           "age": 22, "height": 179 
    };
    await User.remove({});
})

afterEach(async () => await User.remove({}));

it('signs up', async () => {
    await request(inst)
        .post('/api/v1/signup')
        .send(a_user)
        .expect(200);
});

The full stack trace of my error is:

  1) Authentication signs up:
 Error: expected 200 "OK", got 404 "Not Found"

  at _combinedTickCallback (internal/process/next_tick.js:74:11)
  at process._tickCallback (internal/process/next_tick.js:98:9)

Only in tests but using postman works fine. Is there something i'm not doing right?

I'm using koa: 2.0.0, supertest: 2.0.1 and for routes koa-rest-router: 1.0.0.

Please help! Thanks.

Sad, I didn't perform it in "The async/awaits way".

This

userInst.save(async(err, user) => {
        
        if(err) { return next(err); }

        const token = tokenForUser(user);

        ctx.body = token;

        return next();
    });

Had to be

This

const user = await userInst.save();
const token = tokenForUser(user);

ctx.body = token;

return next()

I didn't put an await before userInst.save, causing the function to return an instantly resolving promise.
