telegrambot | A library to use for building Telegram Bots | REST library

You can do this:

I would propose to take a look in the RateLimiter direction. Maybe it does not work as expected, depending on the number of requests your application does over time. From the Javadoc for Ratelimiter: "It is important to note that the number of permits requested never affects the throttling of the request itself ... but it affects the throttling of the next request. I.e., if an expensive task arrives at an idle RateLimiter, it will be granted immediately, but it is the next request that will experience extra throttling, thus paying for the cost of the expensive task." Also helpful might be this discussion: github or github

I could imaginge there is some throttling adding up or other effect in the RateLimiter, i would try to play around with it and make sure this thing really works the way you want. Alternatively, consider using Spring @Scheduled to read from your queue. You might want to spice it up using embedded JMS for further goodies (message persistence etc).

The issue is in your Dockerfile; after the operation COPY ./src/* ./ the directory structure in your image is as follows:

I think you should try to lean on ASP.NET Core to parse your json input. You can simply specify type Update instead of object and it will do the rest for you. You just need to use ready object with type Update:

You have deployed your code as a web process. web processes listen for HTTP requests and must bind to a port provided at runtime shortly after starting up.

Since your bot does not respond to HTTP requests it should not be deployed as a web process. A common name for such processes is worker.

First, remove the web container you have already deployed:

You need to specify the Charset on Scanner. That is probably the problem.

Example:

With the help of @LukeWoodward, I did find my mistake and that upd.getChatMember() was the one responsible for giving me the null pointer exception.

upd.getChatMember() will be null if the messages are coming from direct DMs in Telegram and not from group chats. For that, you need to use upd.getMessage().getFrom().getId() for getting the user's id who direct messaged your bot.

Assuming startBot is a static method on your class:

Pretty simple, just needed to change this library to a https://github.com/rubenlagus/TelegramBots
