Describe your changes
The issue was apparently that the go-genai module expects the roles in the chat history to be either "user" or "model". Since the tool calls in the history were assigned the role "function", combined with the fact that the chat creation errors were being ignored, resulted in this cryptic/weird issue. This pr introduces a workaround by attributing the tool-call's output to the model.
Steps to validate the fix:
PS: I'm not sure if this is a "proper fix", since the tool call results shouldn't most likely be attributed to the model in the history.
