How to globally override catch function?

[Khuzha]

Is it possible to override catch function for whole bot, not in every place I need it through injecting and redefining .catch()?

You can get Telegraf instance anywhere in you app with @InjectBot() decorator, or get it in main.ts:

// main.ts
const bot = app.get(getBotToken());
bot.catch(e => console.error(e));

Also you can use ExeptionFilter's.
