An error is reported when calling deepseek r1

[WoamHuman]

An error occurred while using the deepseek r1 model:{"error":{"message":"The first message (except the system message) of deepseek-reasoner must be a user message, but an assistant message detected.","type":"invalid_request_error","param":null,"code":"invalid_request_error"}}.

In SillyTavern, i can choose api link configuration-prompt post-processing (api链接配置-提示词后处理) or switch to the staging branch (切换到staging分支) to solve the problem, but on risuai, I don't know how to deal with this kind of problem.

Thank you for your help.
