MongoDB connection error: Error: slash in host identifier

Hello, I'm running your node.js project with mongodb, express, but I get this error when I start the server:

MongoDB connection error: Error: slash in host identifier
[nodemon] app crashed - waiting for file changes before starting ...

this is my files:
mongoose.js file:

const { mongo, env } = require('./vars');

// set mongoose Promise to Bluebird
mongoose.Promise = Promise;

// Exit application on error
mongoose.connection.on('error', (err) => {
  console.error(`MongoDB connection error: ${err}`);
  process.exit(-1);
});

// print mongoose logs in dev env
if (env === 'development') {
  mongoose.set('debug', true);
}

/**
* Connect to mongo db
*
* @returns {object} Mongoose connection
* @public
*/
exports.connect = () => {
  mongoose.connect(mongo.uri, {
    keepAlive: 1,
    useMongoClient: true,
  });
  return mongoose.connection;
};

my var.js file:

const path = require('path');

// import .env variables
require('dotenv-safe').load({
  path: path.join(__dirname, '../../.env'),
  sample: path.join(__dirname, '../../.env.example'),
});

module.exports = {
  env: process.env.NODE_ENV,
  port: process.env.PORT,
  jwtSecret: process.env.JWT_SECRET,
  jwtExpirationInterval: process.env.JWT_EXPIRATION_MINUTES,
  masterAccount: process.env.MASTER_ACCOUNT_NUMBER,
  masterAccountPassword: process.env.MASTER_ACCOUNT_PASSWORD,
  mongo: {
    uri: process.env.NODE_ENV === 'test'
      ? process.env.MONGO_URI_TESTS
      : process.env.MONGO_URI,
  },
  logs: process.env.NODE_ENV === 'production' ? 'combined' : 'dev',
};

the index.js file:

Promise = require('bluebird'); // eslint-disable-line no-global-assign
const { port, env } = require('./config/vars');
const app = require('./config/express');
const mongoose = require('./config/mongoose');

// open mongoose connection
mongoose.connect();

// listen to requests
app.listen(port, () => console.info(`server started on port ${port} (${env})`));

/**

module.exports = app;

I have an 401 error (Unauthorized) with this API

I am integrating my API into my ionic view, so I would like to integrate my money transfer endpoint from one leaf port to another but I get a 401 error.

Here is my source code:

---

Ionic Source Code of Transfer:

• This is my Service Allet:

import { Injectable } from '@angular/core';
import { HttpService } from './http.service';
import { StorageService } from './storage.service';
import { Router } from '@angular/router';
import { Observable } from 'rxjs';

@Injectable({
  providedIn: 'root'
})
export class WalletService {

  constructor(
    private httpService: HttpService,
    private storageService: StorageService,
    private router: Router
  ) { }

  transfert(data: any): Observable<any>{
    return this.httpService.post("ewallet/transfer", data);
  }
}

• My httpService:

import { environment } from './../../environments/environment.prod';
import { Injectable } from '@angular/core';
import { HttpClient, HttpHeaders } from "@angular/common/http";
import { headersToString } from "selenium-webdriver/http";

@Injectable({
  providedIn: 'root'
})
export class HttpService {  
  httpOptions = {
    headers: new HttpHeaders({ 
      'Content-Type': 'application/json'
    }),
    withCredintials: false
  };

  constructor(
    private http: HttpClient
  ) {}

  post(serviceName: string, data: any){
    const url = environment.apiUrl + serviceName;
    return this.http.post(url,data, this.httpOptions);
  }

  getById(serviceName: string, id: string){
    const url = environment.apiUrl + serviceName;
    return this.http.get(url+"/"+id);
  }

  getAll(serviceName: string){
    const url = environment.apiUrl + serviceName;
    return this.http.get(url);
  }

  update(serviceName: string, id: string, data: any){
    const url = environment.apiUrl + serviceName;
    return this.http.put(url+"/"+id, data, this.httpOptions);
  }

  modify(serviceName: string, id: string, data: any){
    const url = environment.apiUrl + serviceName + id;
    return this.http.patch(url, data, this.httpOptions);
  }

  delete(serviceName: string, id: string){
    const url = environment.apiUrl + serviceName;
    return this.http.delete(url+"/"+id, this.httpOptions);
  }
}

  .post(authorize(), validate(walletTransfer), controllerWallet.transfer); //authorize(), walletTransfer, 

• The Controller Function:

Any help is appreciated, thanks!
