@vermaankit192 Can you please post The output of rasa --version, and A minimal example of a rasa project that produces this error The command that led to this traceback.

Rasa Version : 2.4.0 Rasa SDK Version : 2.4.0 Rasa X Version : 0.35.1 Python Version : 3.8.5 Operating System : Windows-10-10.0.18362-SP0 Python Path : C:\Users\TTN\AppData\Local\Programs\Python\Python38\python.exe I have a look up table as category.txt inside data folder and lookup_tables subfolder. The content of category.txt is refrigerator washing machine air conditioner I am calling this inside nlu.md as ## lookup:category data/lookup_tables/category.txt When i train my model by python -m rasa train. the above error comes. However, this was not an error when I ran the model 10 days ago. but somehow this code is not working now.

Hi @vermaankit192 Thank you for the details. It looks like you found a Windows-related bug. I created an issue here . Until this is resolved, you will have to paste the lookup lists directly into your file (also we recommend to use yml instead of md; Markdown is deprecated). Sorry for the inconvenience!

[image] vermaankit192: this was not an error when I ran the model 10 days ago Almost overlooked this. Did you update your rasa version or any packages in your environment in between?

Giving path did not work for me either. I created a seperate .yml file for my lookup table and that works. You have to convert txt to yml using a simple script

Can you explain me exactly you resolved it. With sample script as u said and seperate yml means where u created it ?
