Hello, I tell you that I have solved the problem;
the problem was that when following the syntax of the files there was no problem, it was all due to the line breaks between utters
that is to say that I had declared them at the beginning
responses:
utter.......
-text:
-text:
-text:
utter......
-text:
-text:
-text:
utter......
-text:
-text:
and finally what I did is leave no spaces between lines:
responses:
utter.......
-text:
-text:
-text:
utter......
-text:
-text:
-text:
utter......
-text:
-text:
It caught my attention because in the first case only the first n worked, but after n+1 it didn't, until I eliminated the empty lines, I didn't find a reference to this in the documentation, but I think there would have to be a section or notes referring to the syntax rules.
See you, greetings.
