Hello, I keep getting this error when I try to use Kimi with Nvidia NIM api key and from the list of models I can access only the " GPT OSS 20B" model is responding correctly, all other models such as Nemotron 3 super still output the same error.
I even switched agents and it works fine so only in Kimi does this happens. It started when I updated to the latest version.
Thanks for the help ahead.
