can't return error as json in express

[skyshy0707]

Hello! Your Http error classes can't work properly in Node.js express 5.2.1 version.

in my api.js:

const express = require('express')
const app = express()
app.use(express.json())

const authentification = express.Router()

authentification.post('/signin', basicAuth, async (request, response) => {
  return await crud.signin(request, response)
})
//...

in my crud.js:

const status = require('./status')
async function signin(request, response){

    try{
         const jwtCredentials = await auth.jwtAuth.recordCredentials(request)
    }
    catch (error) {
         status.token_not_provided()
    }
    return response(201).json(jwtCredentials)
}

in my status.js:

const { HttpError } = require('http-json-errors')

module.exports = {
        token_not_provided: (detail=null) => new HttpError(
              401, {
                   message: 'Token wasn\'t provided',
                   detail: detail
             }
       ),
}

I get correct error code but http response isn't jsonable, it is a plain html text.
