I looked at this thread which is reporting the same error but it’s not clear how it was fixed. So I am raising it again here to get some help …
I am running the following versions:
rasa 2.8.1 rasa-sdk 2.8.1 rasa-x 0.42.0
I am using Ubuntu 18.04 and running Python 3.6.9.
I have tried deleting the events and rasa db files (which previously worked for me) via this thread but I’m afraid it still doesn’t work. I had the same error with rasa 2.7.1 and corresponding SDK and rasa-x versions from the compatibility matrix.
Can anybody help?
