I just did some major surgery on my functions (in Python), and somehow I'm getting this error: Error: Invalid response object from API: '{"helicone-message":"Helicone ran into an error servicing your request: TypeError: Cannot read properties of undefined (reading 'replace')","support":"Please reach out on our discord or email us at help@helicone.ai, we'd love to help!","helicone-error":"{}"}' (HTTP response code was 500)
OpenAI API returned an API Error: Invalid response object from API: '{"helicone-message":"Helicone ran into an error servicing your request: TypeError: Cannot read properties of undefined (reading 'replace')","support":"Please reach out on our discord or email us at help@helicone.ai, we'd love to help!","helicone-error":"{}"}' (HTTP response code was 500)

I have inspected my inputs and none of my input values are undefined. Would love any pointers to figure out what's going wrong and how to resolve the issue.
