通过接口Api执行工作流报错如下,

got prompt
[Impact Pack] ComfyUI-Impact-Pack: Error on prompt - several features will not work.
'list' object has no attribute 'items'

但通过comfyui界面执行是正常的,这是因为自动隐式兼容处理了,工作流设计不规范,导致某些节点列表和字典返回值混淆,导出.json时,数据是严格按照JSON结构来的,没有GUI的自动纠正机制,所以会报错.

最后排查到 报错的节点如下


"25": {
  "inputs": {
  },
  "class_type": "PulidEvaClipLoader",
  "_meta": {
    "title": "PuLIDEVAClip加载器"
  }
},

由于25号节点 inputs为空,默认返回了空list,而非字典类型dict,但是PulidEvaClipLoader插件要求输入为字典类型

实际操作改为如下,增加默认值即可

  "25": {
  "inputs": {
    // 添加任意有效字段占位（例如模型路径）
    "dummy_param": "none"  
  },
  "class_type": "PulidEvaClipLoader",
  "_meta": { "title": "PuLIDEVAClip加载器" }
}
