import { Bot } from "https://dotland.deno.dev/x/grammy@v1.20.2/mod.ts";
Sets the bots error handler that is used during long polling.
You should call this method to set an error handler if you are using long
polling, no matter whether you use bot.start or the @grammyjs/runner
package to run your bot.
Calling bot.catch when using other means of running your bot (or
webhooks) has no effect.
