Hi, I’ve encountered a problem when processing the unhappy path. As shown in the figure, my NLU model correctly classified my intention “explain”. I hope that rasa can run “action\_explain\_score\_form” as written in my story.However, the bots wants to run ‘score\_form’,so I got a error “Failed to extract slot”. what should I do, anyone help me?

Unfortunately I do not recognize the language that is being typed here so it is really hard to debug for me. If it is complaining about a slot not being extractable … can you confirm that the slot is at least set? Again, I don’t understand the language here unfortunately so I can’t help much more here.
