I have similar issue if not the same, I may be wrong but it seems something is wrong with the State. I tried with Gemini Flash in addition to ollama qwen2.5-coder:32b and its the same.

I think this is to do with override variables. You now have to configure them in your global variables, you can't just declare them on the fly. so I add a couple empty objects for things I want to declare in api calls and then in my chatflow config I can toggle them to allow for overwriting
