Ruby Telegram bot fails with NoMethodError when ‘/start’ is sent. Use this modified code:
require 'telegram/bot'
api_key = 'YOUR_TOKEN'
Telegram::Bot::Client.run(api_key) do |client|
client.listen do |msg|
client.api.sendMessage(chat_id: msg.chat.id, text: 'Hello!')
end
end
I encountered a similar issue in a project recently and found that the error was often related to incompatibilities between gem versions. In my case, updating the telegram-bot-ruby gem resolved the issue. It turned out that the method being used had been updated or deprecated in a newer version. It is useful to check the project’s repository for documentation or any breaking changes that have been noted by other users. Double-checking your installation and ensuring device token correctness has also played a key role in addressing these kinds of errors.
hey, try verifying your gem dependencies. i once had a similar bug and reinstalling the gem fixed it. also, check if all modules are properly updated. maybe your method was deprecated in the version you’re using. good luck!
I encountered a similar problem in another project, and for me, it turned out to be related not only to gem versions but also to the order of initializing the client methods. I spent some time adding logging to each step of the bot’s workflow, which revealed that some parts of the message payload were not as expected when handling commands like /start. This approach helped me pinpoint missing or nil objects. I later discovered that a specific patch in a dependency was crucial in ensuring the correct method routing, so a thorough review of your library versions and initializations might provide the solution.
I encountered a similar problem in another project, and for me, it turned out that the issue was partly due to how the client object was initialized. I eventually discovered that while my gem versions were correct, the key problem was with the API token handling, which prevented some necessary methods from getting properly set up. Adding more granular error reporting to capture nil values in the objects helped me pinpoint where the process diverged. I recommend monitoring the responses from early in the client setup to ensure that every property you rely on is actually defined before calling any methods on it.
