openAI模型调用报错 you must provide a model parameter

配置了openai的模型模板，调用时提示：
错误："Workflow execution failure: error, status code: 400, status: 400 Bad Request, message: you must provide a model parameter"
更换过模型，也重新下载了模版文件，报错都是一样的

Start by reproducing the workflow failure using the OpenAI model template and configuration described in the issue, then trace the workflow's model-call entry point. Compare the generated request with the attached error and verify that a valid model parameter is sent. Done means the configured model runs without the 400 error.
