Hello, I have an Array[File] and a File. How can I add this File into the Array[File]? Iterating would result in two Files, and I can’t merge them back into Array[File].
Because ComfyUI’s workflow only accepts images in the form of Array[File]. I have two image upload nodes, one image is generated by the previous ComfyUI as an Array[File], and the other is a user-uploaded image (File). Both images need to be passed to the next ComfyUI node, but Array[File] and File cannot be combined.
刚好前几天也在捣腾 Array ( 作为 File 类型 现在 dify 的操作还是不太方便）
有两个思路你可以参考一下：
看看大家还有什么其他好办法
