preparedMessage.setChatId(message.getChatId());
preparedMessage.setText(String.join("\n", eventsStringList));

InlineKeyboardMarkup markupInline = new InlineKeyboardMarkup();
List<List<InlineKeyboardButton>> rowsInline = new ArrayList<>();
List<InlineKeyboardButton> rowInline = new ArrayList<>();
rowInline.add(new InlineKeyboardButton().setText("test1").setCallbackData("update_msg_text"));

I encountered the same problem. When I downgraded to version 4.2, it seems to work.
