问题描述 执行画图命令时，返回的是会话信息。

复现步骤

在本地进行curl：

$ curl http://127.0.0.1:7077/v1/images/generations   -H "Content-Type: application/json"   -H "Authorization: Bearer sk-xxx"   -d '{
"model": "gpt-4",
"messages": [
  {
    "role": "user",
    "content": "画一只猫 \\n"
  }
]
}'
{"error":{"message":"Failed to fetch image URL, please try again later.","type":"request_error","param":"","code":"500"}}

在discord里观察，只进行了文本会话。没有走画图接口。

查看容器日志，其实是发送了image的请求了的。 $ docker logs -f 523 [SYS] 2024/03/25 - 22:09:25 | COZE-DISCORD-PROXY v4.4.0 started [SYS] 2024/03/25 - 22:09:25 | Environment variable check passed.
