I’ve attempted to use action\_back, I saw it referenced here: [Default Actions](https://rasa.com/docs/rasa/default-actions/) Is there a guide available on how to trigger it? I tried just entering /back into the command line and nothing was picked up. Then I created an intent called /back, trained it, and triggered it but nothing happened there either. Any help would be much appreciated Is this feature still supported? ---

@ronankff Hi. I will suggest make an intent like `go_back`, and then trigger like this ```auto go_back: triggers: action_back ``` ``` actions: - action_back ``` ---

Thanks for the reply @nik202, I’ll give that a shot ---

Hey @nik202, I set up the bot as you said. Can you confirm for me that this is the way the back function works: ![output](https://europe1.discourse-cdn.com/flex013/uploads/rasa/original/2X/6/61e51b12d77242931807fed9d5e76ee8652959c2.png) Story is as follows: ![output2](https://europe1.discourse-cdn.com/flex013/uploads/rasa/original/2X/f/f70b22d2584555dcfe7674b89a2cd761669de467.png) ---

@ronankff have you updated config.yml file **action\_back** ([Default Actions](https://rasa.com/docs/rasa/default-actions#action_back)) This action undoes the last user-bot interaction. It can be triggered by the user by sending a “/back” message to the assistant if the [RulePolicy](https://rasa.com/docs/rasa/policies#rule-policy) is configured. ``` policies: - name: "RulePolicy" core_fallback_threshold: 0.3 core_fallback_action_name: action_default_fallback enable_fallback_prediction: true restrict_rules: true check_for_contradictions: true ``` In your stories, you not mention action? I guess you using Rasa 1.X ? Right? If you are using Rasa Open Source please updated to Rasa 2.7.1 or 2.6.2 ---

I am using 1.x, apologies I forgot to even mention that. Unfortunately we’re not in the position to upgrade versions right now. According to the Legacy docs the correct policy for this action is MappingPolicy, which I have included ![config](https://europe1.discourse-cdn.com/flex013/uploads/rasa/original/2X/2/28b61dbd9d9e2c3185aaa3d6595f1b2ce83ba22f.png) Good spot with the stories file too, I changed it. ![newstory](https://europe1.discourse-cdn.com/flex013/uploads/rasa/original/2X/7/7505782c8267002738f07238075cd48f25d9636b.png) Running with the above setup gets me this error: I’m a bit confused because as far as I can tell action\_back doesn’t need to be initialised in the actions file. ![error](https://europe1.discourse-cdn.com/flex013/uploads/rasa/original/2X/5/53fcee88d3f3c116577465df2bc052c1ac6555d1.png) ---

@ronankff did you mention this in domain.yml? ``` actions: - action_back ``` Is your action\_back is a function in action.py with trigger utterance? An alternative solution, if you want to go back to the previous menu. In that, I can help if you want? For Rasa Ver 1.X **For example:** **Bot:** How are you doing? or some menu Rasa | Rasa X **User:** I’m fine Button: previous menu **User:** user select previous menu **Bot:** How are you doing? or some menu Rasa | Rasa X and so on. I am sorry, a lot have change from Rasa 1.x to Rasa 2.7.1. It’ bit confusing for me also 😛 But, I honestly want to assist you @ronankff ---

Yes, I have the action registered in the domain. My action\_back is not a function in action.py yet. I thought that it would be built into Rasa as it’s a default action. Do I have to create it myself? If so, what code do I need? Thank you for offering an alternative but I the product owner wanted something that would take you back in the conversation. For example: - User - Hello - Bot - Hello, how can I help? - User - See menu - Bot - _menu options_ - User - /back - Bot - Hello, how can I help? Does that make sense to you? ---

@ronankff using rasa-x? Hope you aware of this You can install Rasa Open Source using pip (requires Python 3.6, 3.7 or 3.8). Its fine if your rasa x is running on python 3.9 ---

I’m not using rasa x for this particular task. I’m just trying to make a small demonstration of the back button working and then we’ll add it to the larger project once we know it works. ---

When you say “go back”, “back”, "put me back " Please consider this (back option) process (dialogue conversation) based on the project. Can I ask what’s are your project objective? I have taken this thread [How to use action\_back? - #9 by ronankff](http://forum.rasa.com/t/how-to-use-action-back/45268/9) as a example and checked and fixed your code. Please give me more example(as shown in above thread) so that I can help you more. Thanks. ---

Oh no problem man, I appreciate the help. Ideally what they want is that the bot goes back to the previous step. That’s why I’m trying to get action\_back working. The project has a lot of conversations and sometimes people press the wrong button or whatever and want to go back and hit the right button. ---
