UnrecognizedPropertyException: Unrecognized field "is_bot"

When I start the bot using bot.start(); I get this Exception: (I censored my data using "xxxxxxxxx")

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "is_bot" (class io.fouad.jtb.core.beans.User), not marked as ignorable (4 known properties: "first_name", "id", "last_name", "username"])

The same issue.

Same issue here! But I could fix the error by adding several json keys to the user/message/chat class. Try adding the missing ones that are stated out by the error messages in the log or look up the json schema at the official telegram page.

me too

To fix this, add this the following line to all three io.fouad.jtb.core.utils.JsonUtils.toJavaObject(...)

mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

This will ignore all future fields Telegram adds on their future updates.

Hm. This library should be updated more I guess...

Here's a recompiled core jar with the fix applied.
