+sqlite3.InterfaceError: Error binding parameter
+===============================================
+
+This error occurs when you pass a chat id value of the wrong type when trying to call a method. Most likely, you
+accidentally passed the whole user or chat object instead of the id or username.
+
+.. code-block:: python
+
+    # Wrong. You passed the whole Chat instance
+    app.send_message(chat, "text")
+
+    # Correct
+    app.send_message(chat.id, "text")
