Hello! I have an issue finding the best spot to intervene in the rasa flow. My use case is that I want to alter the user’s message text in a specific case, more exactly, when a certain entity is found. At first, it seemed that the logical place to do that was in a custom nlu component. And indeed, that’s where one add information for future processing in the nlu pipeline. But as it turns out, the only thing that cannot be changed is the text of the message, and I think it is because of this line: rasa/processor.py at f3a3fb7ab391482da5ae7f6f789f0a8c7d600f8b · RasaHQ/rasa · GitHub if it would be parse_data.text, the situation would’ve been resolved Also, the log following also adds the received text instead of the changed one. Dummy example: user says hi nluComponent does if message.text == hi: message.text = "Hello" This being the situation, I have some open questions: Is it intended that you cannot change by all means the user text at this level? Is there a better place to alter user input? It can be done in a custom policy, but it really feels wierd to alter the tracker. Is there a way to implement a custom tracker? (maybe if there is no other evident solution, this would be a better workaround) PS: This is a very specific use case and the example is just to prove the technical situation, not the functional one.

Hi!

You have two ways to do it. Make the change in frontend, when the user click “send” and frontend make post to rasa or…

Build a custom channel to do it
