Error: Password contains an illegal unescaped character: using loopback-connector-mongodb: ^5.5.0

[mercale]

Steps to reproduce

The solution stated in PR#529 does not seem to work for me.

Here is my config.
Noticed the last char in password was and equal sign "=" I encoded this with %3D but I am still getting error.
What am i doing wrong? Can someone help me figure it out please?

So userid and password are pre-generated by mongo-atlas on azure.

const config = {
  name: 'backendDB',
  connector: 'mongodb',
  url:  "mongodb+srv://aef38798-4404-4864-93ce-a742deee9833:oN4GmVQ96CsEIBzcPbcEeYU4V74D5-7V7V1tqSBt0v4%[email protected]/default",
    useNewUrlParser: true
};

I really need help, :( anyone?
I've tried all the posted solutions for this subject, but still getting this pesky error Password contains an illegal unescaped character. I've encoded the password but that doesn't help either. Help anyone?

here is my loopback code, generated by lb4 datasource for mongodb:

import {inject, lifeCycleObserver, LifeCycleObserver} from '@loopback/core';
import {juggler} from '@loopback/repository';

const config = {
  name: 'backendDB',
  connector: 'loopback-connector-mongodb',
  url:  'mongodb+srv://381761ba-9143-4822-94d4-e740ed4519ec:K4d5oeWrqMZW86mGq02cs5kyFTrc2VoD6l_6v-30cyw%[email protected]/default',
  useNewUrlParser: true
};
// Observe application's life cycle to disconnect the datasource when
// application is stopped. This allows the application to be shut down
// gracefully. The `stop()` method is inherited from `juggler.DataSource`.
// Learn more at https://loopback.io/doc/en/lb4/Life-cycle.html
@lifeCycleObserver('datasource')
export class BackendDbDataSource extends juggler.DataSource
  implements LifeCycleObserver {
  static dataSourceName = 'backendDB';
  static readonly defaultConfig = config;

  constructor(
    @inject('datasources.config.backendDB', {optional: true})
    dsConfig: object = config,
  ) {
    super(dsConfig);
  }
}

Hi @mercale, this repo is for the older EOLed LoopBack 3 framework and isn't being actively monitored. LoopBack 4 is under https://github.com/strongloop/loopback-next.
