本地部署，接入多模态模型一直报错

本地部署coze，接入视觉模型，传入image_url，大模型节点一直报错{
"$error": "Workflow execution failure: json: cannot unmarshal string into Go struct field ChatCompletionResponse.created of type int64"
}
该如何修改代码以适配

Start at the Go ChatCompletionResponse.created field and reproduce the local deployment workflow with the visual model and image_url. Trace the response-decoding path; done means the reported response no longer fails with the shown unmarshal error, with coverage for this response shape.
