Hello, obviously you are trying to process a telegram message, meaning that you use Telegram.
By some natural coincidence, the fastest possible way to get help is via Telegram.

Please, make sure you enter ur Telegram public chat.

as per your question, yes the best thing you can do to analyze your bot behavior, is to analyze your logs, this is what you did.

So the log says your message is too long, meaning, that somewhere there is a setting in Moonbot, that defines how long should your signal messages be, otherwise they are not treated as signals.

Settings - Autobuy tab - lower part, next to the keywords, check the Message length slider.

Cheers!
