Hello, it seems like whever i try to use a thinking model such as the latest deepseek v4-pro or moonshot’s kimi k2.6 or whatever AI on a thinking mode it just fails the request doesn’t work.
Bad request - please check your parameters
The reasoning_content in the thinking mode must be passed back to the API.
Does anyone know the solution to this?
Hi @elalamiimed
Can you share your workflow?
I’ve created a community node that solves this.
The description is in Portuguese (Brazil), but the fix is simple: just select “no reasoning” and you can use it without getting the “The reasoning_content in the thinking mode must be passed back to the API” error.
