The only difference from a working file, and a file that throughs an error is this nlu:
at the second line:
version: "2.0"
nlu: # Do not remove, else rasa will ignore the file...
stories:
##
## Form: Departure
##
- story: flight departure information - unhappy path - stop - el
If I delete this line, I get the error above. I am not sure if this error is generated without --debug
in rasa train
. (I always use it).
