I used the above code but still I am not able to get the value. If the sentence structures are various, should it be entities extraction? However, I’ve searched the forum and found a few guys have the similar entities extraction problems. For example, entities extraction problem But no one is able to help.
On the other hand, if I set it as firm when the bot asking like “please fill in the blank, my topic is ______ ?” Then I should use “FreeTextFormField” with "tracker.latest_message.get("text")? But this seems the bot is stupid though.
