调用stable diffusion webui工具进行绘图失败“Failed to generate image”

[fengyingbanbo]

stable diffusion webui 监听的端口是7862

配置的是http://192.168.3.37:7862/，已经授权成功

大语言模型用的llama3:8b，调用stable diffusion web ui工具返回{"stable_diffusion": "Failed to generate image"}

The default index value of webui is incorrect. Modify it directly in the dify/api/core/tools/provider/builtin/stablediffusion/tools/stable_diffusion.py
