Getting this error Core training was skipped because no valid domain file was found

Core training was skipped because no valid domain file was found. Only an NLU-model was created. Pleas e specify a valid domain using the ‘–domain’ argument or check if the provided domain file exists.

@insightskillz Hi, you need to check the domain file syntax using and need to mention the intent and action. Further, can you share the full error, it is very hard to tell without seeing the full screen or error or run rasa in debug mode?

@insightskillz can I request that you re-formatted the second last post for me, look like paragraph to me and hard to understand the code. @insightskillz how you running the rasa x, which command you using? is this query related to rasa open source or rasa-x? or you using rasa shell --debug?
