Hey @gcgloven, thanks for replying. I found the solution to my problem. Actually the domain.yml file was an invalid yaml file because of some extra spaces in it. Because of this, I got the error “domain file not found”.
I found this by using the command “rasa data validate”
One more reason to get this error could be duplicated keys in the domain.yml file. To check this,
1). The yamllint command-line tool using sudo pip install yamllint
2). Run yamllint domain.yml and check for
336:3 error duplication of key “utter_greet” in mapping (key-duplicates)
