MappingPolicy throwing error

See original GitHub issue

Rasa version: rasa-core==0.14.0 rasa-core-sdk==0.13.1 rasa-nlu==0.15.0

Python version:

Python 3.6.5 :: Anaconda, Inc.

Operating system (windows, osx, …): OSX 10.13.6 Issue:

Some of my mappings cause MappingPolicy to throw an error. Haven’t been able to isolate the issue properly (this error happens for intents greeting, goodbye, availableFunctions, but not for getBalance, see yml files below):

@erohmensing are you opening a PR for this? please do so off of 0.14.x on the rasa_core repo

Okay great, thank you! As predicted, it successfully predicts utter_greet, it just gets messed up when it tries to predict the next action after. I’ve checked it out locally and get the same stuff, so your fix should work. Thank you!
