[v0.0.15] LLMstack NoneType error in Chatbot

[Moep90]

Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. CreateWebsite Chatbot from Template
2. Add Datasource of Company website
3. Check "use local ai if available"
4. Change using Model to gpt-3.5-turbo
5. Enter preview mode
6. Ask What is the VAT of Company? AI responds with

I'm sorry, but I don't have access to the current VAT rates of Company. However, you can check the official website or contact their customer support for more information.

7. Ask What is the VAT Number of Company? multiple times
8. see error llmstack.processors.providers.promptly.text_chat.TextChatOutput() argument after ** must be a mapping, not NoneType

Expected behavior
I expect LLMstack to scrape the website for a VAT Number and return it back
