[BUG] Unhandled Exception: PlatformException(17, request to join channel is rejected, null, null)

[Nader2004]

Hello, while just running the basic example:

import 'package:agora_uikit/agora_uikit.dart';
import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final AgoraClient client = AgoraClient(
    agoraConnectionData: AgoraConnectionData(
      appId: "<--My App Id-->",
      channelName: "test",
    ),
    enabledPermission: [
      Permission.camera,
      Permission.microphone,
    ],
  );

  @override
  void initState() {
    super.initState();
    initAgora();
  }

  void initAgora() async {
    await client.initialize();
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Agora UIKit'),
          centerTitle: true,
        ),
        body: SafeArea(
          child: Stack(
            children: [
              AgoraVideoViewer(
                client: client,
              ),
              AgoraVideoButtons(
                client: client,
              ),
            ],
          ),
        ),
      ),
    );
  }
}

I couldn't join the channel with this error :
Unhandled Exception: PlatformException(17, request to join channel is rejected, null, null)
Although I have read the docs about error code 17 at https://docs.agora.io/en/Video/error_rtc?platform=Flutter
Non of the the mentioned causes were used or exist in the basic example

@Nader2004 This error occurs when the user hasn't left the channel and you're trying to join the channel again. Make sure that you disconnect the call and leave the channel before joining again.
