Error 500 (no body) on all requests

Hello,
I had a config.yaml working just fine with Chat Plan and Agent, but recently (a week ?), I have had this error on each prompt. I use a Qwen3-30B model. In the logs, there are messages about config.yaml not getting seen by the AST tracker. I tried going back to older version of Continue but it changed nothing. My API is accessible through other services.
