ModuleNotFoundError: Cannot find class 'RegexEntityExtractor'

I am using RASA docker image rasa/rasa:1.10.12-full with below pipeline. Getting error during training. Is it due to RASA core version issue or something else.

Exception: “ModuleNotFoundError: Cannot find class ‘RegexEntityExtractor’ from global namespace. Please check that there is no typo in the class name and that you have imported the class into the global namespace.”

Config.yml language: “en”
