Please follow the steps as explained: https://github.com/rubenlagus/TelegramBots/wiki/How-To-Update#to-version-242

Thanks!

[segator]

same problem, How to update doesn't work in my case
I'm using spring boot and Maybe is causing conflicts.

@SpringBootApplication
public class AutoDownloaderApplication implements CommandLineRunner {

    @Autowired
    private MovieGrabber movieGrabber;

    @Override
    public void run(String... args) throws Exception {
        ApiContextInitializer.init();
        TelegramBotsApi botsApi = new TelegramBotsApi();
        botsApi.registerBot(movieGrabber);

    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(AutoDownloaderApplication.class, args);
    }
}

Try moving ApiContextInitializer.init(); to a static {} block. Or put it somewhere to run earlier.

[segator]

Thank you, it works :)

[sslavian812]

@drunckoder can you please explain, why ApiContextInitializer.init(); should be moved to static block?
I used the following code in PostConstruct-annotated method of my bot-Bean class in SpringBoot.

ApiContextInitializer.init();
TelegramBotsApi botsApi = new TelegramBotsApi();
botsApi.registerBot(this);

I got the same error and your advice did help me too. Why?)

[v1as]

@sslavian812 This is because it is necessary to init ApiContextInitializer before constructor of your bot. In your case you calling it in PostConstruct block, which executing after constructor executing.

[charmstead]

I solved this by removing the annotation @component or @service from myBots class

[lawrence615]

@charmstead I also solved the same problem by removing the annotations; but what if you would want to autowire something like a repository in myBots class. How would you go about it?

[the-elf]

@charmstead I solved this problem by putting ApiContextInitializer.init() before SpringApplication.run

[IgorVolg1n]

@charmstead any idea, why does it work?
and are there some hidden pitfalls in this solution?
thanks in advance

@log4j2
@service
public class TelegramBotService extends TelegramLongPollingBot {
@Autowired
private TelegrambotConfig telegrambotConfig;
@Autowired
private TelegramInvoker telegramInvoker;

@PostConstruct
public void registerBot(){
    TelegramBotsApi botsApi = new TelegramBotsApi();
    try {
        botsApi.registerBot(this);
        log.info("==================================TelegramBotService.afterPropertiesSet:registerBot finish");
    } catch (TelegramApiException e) {
        e.printStackTrace();
    }
}


@Override
public void onUpdateReceived(Update update) {
    
    if (update.hasMessage() && update.getMessage().hasText()) {
        telegramInvoker.action(update);
    }
}

@Override
public String getBotUsername() {
    return telegrambotConfig.getName();
}

@Override
public String getBotToken() {
    return telegrambotConfig.getToken();
}

}

@SpringCloudApplication
public class Application {

public static void main(String[] args) {
    ApiContextInitializer.init();
    SpringApplication.run(Application.class, args);
}

}

In this way ,I find the sloution

[alexIslander]

In Springboot Telegram starter version 4.1, you don't need to register your bot! It is done automatically!

[mhkarimi]

I had a same problem, just add this to your main springboot class :

@PostConstruct
    public void init(){
        ApiContextInitializer.init();
    }

[AppLoidx]

Suddenly someone will help. I had such an error when there was such a piece of code:

DefaultBotOptions botOptions = ApiContext.getInstance(DefaultBotOptions.class);

Maybe you, too, have lost something like this or something similar.

What is the coolest thing is that I called it up to the bot constructor 😫

i have same problem, but i fix by add /lib directory with dependencies, my maven build:

As @sslavian812 mentioned, the problem is in that Bot(TelegramLongPollingBot in my case) constructor was called before the ApiContextInitializer.init();.
Bot constructor expects that context is already initialized.
In my case constructor was called because of Spring DI.
So, if you want to use @Service, @Component, etc. annotations inside the bot class, put

static {
    ApiContextInitializer.init();
}

into bot class to initialize context API context at static initialization stage.
Or like in @pengchenxue example, run this code inside main() before SpringApplication.run(Application.class, args);.

[JimyDeveloper]

Try moving ApiContextInitializer.init(); to a static {} block. Or put it somewhere to run earlier.

thak you. it worked

[torvicv]

I solved removing Autowired of TelegramBot class.

`/@Autowired
private TelegramBot telegramBot;/

TelegramBotsApi botsApi = new TelegramBotsApi();
botsApi.registerBot(new TelegramBot());`

And inserting in registerBot (class) directly.
