hi @prakashr - can you please share a minimal example that causes this error? does it happen with the moodbot (which you create with `rasa init` ? ) ---

Please note that this generic error message can be cause due to missing/incorrect indent as well. For example in the domain.yml file if you code > - affirm: > use\_entities: true and miss adding the indent in the line 2 then during rasa train one will get similar error message. So please check your updated files for such errors, to spot the cause. ---

Faced two times, first it was indent issue in one of the .yml file. second, in domain.yml under intents - EXTERNAL\_reorder\_callback: i was using this, so i changed it to - EXTERNAL\_reorder\_callback: use\_entities: true and it worked ---
