"Describe the model" fails with error after running a simulation of another model

[dmccloskey]

Describe the bug Asking the chatbot to "Describe the model" results in an application error. The error never seems to occur after starting a new Code Ocean instance, but occurs after simulation two models.

To Reproduce Steps to reproduce the behavior:

1. Run the streamlit application
2. Ask the chatbot to e.g., "simulate model 64 ..."
3. Ask the chatbot to "Describe the model" (works)
4. Ask the chatbot to e.g., "simulate model 104 ..." or refresh the webpage
5. Ask the chatbot to "Describe the model" (fails)
