Hey, the problem is solved. It was my mistake. Not Rasa’s mistake.
It was the index.html file in which I set the slots hard:
This is how it used to be:
res.value = `/${slot}:{"${slot}": "${res.value}"}`; // here I set the slot in the frontend
socket.emit('user_uttered', {message: res.value});
This is how it should be:
res.value = `/${slot}{"${slot}": "${res.value}"}`; // here I set the slot in the frontend
socket.emit('user_uttered', {message: res.value});
Thanks for all your help! I really appreciate it!
