Use Knowledgebasebot find question：UnicodeDecodeError: 'gbk' codec can't decode byte 0xa5 in position 641: illegal multibyte sequence
Hi @usst, looks like it was already fixed 22 days ago: rasa-sdk/storage.py at master · RasaHQ/rasa-sdk · GitHub
So updating your rasa and rasa-sdk versions should fix it.
Great debugging though!
