I occur this problem just while typing my first text in slack. The error occurs only with slack.
To resume, I tried to test my bot through slack by running actions then the server and finally ngrok server. Once I type my first text in slck I receive the described error.
Hello @erohmensing,
I had the same issue here with 1.10.0 version of Rasa and slack api.
My question is, If i must upgrade the version of Rasa from 1.10.0 to the 2.1.0 , Am I supposed to re-write and change the structure of all my nlu files and stories files so that they match with the newest structure of rasa 2.1 ? Or is there is any other solution to satisfy compatibility of my project files without rebuilding the project ?
Unfortunately the fix is only available on 2.1. 2.1 should still load old Markdown stories/nlu files, although they are deprecated – meaning you should spend time to migrate them at some point. But you should be able to upgrade to test it without changing too many things as most data formats/policies were deprecated, not removed. (previously deprecated policies such as Keras were removed, however)
so any version >= 2.1.0
